It is forbidden to cook meat and milk together and to partake of them according to Scriptural Law.1Sefer HaMitzvot (negative commandments 186-187) and Sefer HaChinuch (mitzvot 113 and 92) include these prohibitions among the 613 mitzvot of the Torah. It is forbidden to benefit from [such a mixture]. It must be buried. Its ashes are forbidden like the ashes of all substances that must be buried.2See Hilchot Pesulei HaMukdashim 19:11,13.Whenever a person cooks an olive-sized portion of the two substances together,3I.e., together the mixture is the size of an olive. It is not necessary that one have an olive-sized portion of milk and an olive-sized portion of meat. he is worthy of lashes, as [Exodus 23:19] states: "Do not cook a kid in its mother's milk." Similarly, a person who partakes of an olive-sized portion of the meat and milk that were cooked together4If, however, the meat and milk have not been cooked together, there is no Scriptural prohibition against partaking of them together (Maggid Mishneh). According to Rabbinic Law, it is forbidden to partake of them in any manner. is worthy of lashes even though he was not the one who cooked them.5Even if a prohibition was not violated when cooking them together (e.g., they were cooked by a gentile), it is forbidden for a Jew to partake of the mixture. The implication is that the prohibitions against cooking the mixture and partaking of it are separate issues that do not necessarily share a connection (Maggid Mishneh).

The Torah remained silent concerning the prohibition against partaking [of meat and milk]6I.e., no where in the Torah does it state that it is forbidden to partake of such a mixture. only because it forbade cooking them. This is as if to say: Even cooking it is forbidden, how much more so partaking of it.7Significantly, in his Sefer HaMitzvot, loc. cit., the Rambam explains that the prohibitions against partaking of and benefiting from milk and meat are derived from the fact that the Torah repeats this prohibition three times. Perhaps the reason the Rambam does not mention this means of derivation here is to avoid the following question being raised: Why are lashes not given for benefiting from milk and meat?To explain: In Chapter 8, Halachah 16, the Rambam writes that one is not liable for lashes for deriving benefit from a forbidden substance. As explained in the notes to that halachah, the Maggid Mishneh explains that one is liable for lashes only when he derives benefit from the food in an ordinary manner from food. This includes only eating and not other forms of deriving benefit. Nevertheless, seemingly this should not apply with regard to benefiting from a mixture of milk and meat. For, as stated in Chapter 14, Halachah 10, in that instance, one is liable even if one does not derive benefit in the ordinary manner. Hence, it would appear that one should be liable for lashes for partaking of such a mixture.
Among the explanations given why one is not liable is that the prohibition against deriving benefit from a mixture of milk and meat is derived from an inference from a more lenient instance to a more stringent one (a kal vichomer; see Chullin 115b). And we follow the principle that punishment is not meted out when a prohibition is derived in such a fashion, only when it is stated explicitly (Sifri, Naso). If, however, there was an explicit prohibition in the Torah teaching us that deriving benefit from a mixture of milk and meat was forbidden. Seemingly, one would be liable for lashes (Lechem Mishneh). [To cite a parallel:] The Torah did not mention the prohibition against relations with one's daughter, because it forbade those with the daughter of one's daughter.8See Hilchot Issurei Bi'ah 2:6.

According to Scriptural Law, the prohibition involves only [a mixture of] meat from a kosher domesticated animal9With regard to the meat or milk of a kosher wild beast or fowl, see the following halachah and notes. and milk from a kosher domesticated animal, as implied by the verse: "Do not cook a kid in its mother's milk."10I.e., the prohibition involves only a kid that could be eaten and milk of which one could partake. The term "a kid" includes the offspring of an ox, the offspring of a sheep, and the offspring of a goat unless the verse states explicitly, a goat-kid.11I.e., the term gidi translated as "kid," commonly means "a kid-goat." Nevertheless, according to the Bible, it is not necessarily restricted to this meaning unless the verse specifies so explicitly, as in Genesis 27:16; 38:20. The term "a kid in its mother's milk" [does not exclude all other situations].12I.e., the intent is not that one is liable only for cooking an offspring in the milk of its mother and not in any other situations. See the conclusion of the following halachah. Instead, the Torah is speaking regarding the commonplace circumstance.With regard to the meat of a kosher animal which was cooked in the milk of a non-kosher animal or the meat of a non-kosher animal which was cooked in the milk of a kosher animal, by contrast, cooking is permitted, and deriving benefit is permitted. One is not liable for [transgressing the prohibition against partaking of] meat and milk if one partakes of it.13Needless to say, one is liable for partaking of the non-kosher meat or the non-kosher milk.

Similarly, the meat of a wild beast and the meat of a fowl together with the milk of a wild beast or the milk of a domesticated animal is not forbidden according to Scriptural Law.14There is a difference of opinion among the Rabbis in Chullin 116a whether the prohibition against eat the meat of a wild beast [cooked] in milk is Scriptural or Rabbinic in origin. According to some interpretations, that difference of opinion is perpetuated among the Rishonim (see Siftei Cohen 87:4). Nevertheless, the overwhelming majority of Rishonim and Achronim follow the opinion the Rambam states here. This is also the ruling of the Shulchan Aruch (Yoreh De'ah 87:3).Significantly, in (Hilchot Mamrim 2:9), the Rambam states that the meat of a wild beast that is cooked in milk is forbidden according to Scriptural Law. In their glosses to Hilchot Mamrim, the Radbaz and the Kessef Mishneh explain that there, the Rambam is speaking theoretically: Were the halachah to follow the opinion that the meat of a wild beast is forbidden according to Scriptural law, the ruling would be such and such. The Merkevat HaMishneh, however, maintains that a printing error crept into the text in Hilchot Ma'achalot Assurot and the text should be changed to fit the Rambam's ruling in Hilchot Mamrim. Therefore it is permitted to cook it and it is permitted to benefit from it. It is forbidden to partake of it according to Rabbinic Law so that people at large will not be negligent and come to violate the Scriptural prohibition against milk and meat and partake of the meat of a kosher domesticated animal [cooked] in the milk of a kosher domesticated animal. For the literal meaning of the verse implies only the meat of a kid in the milk of its actual mother.15Hence were the Sages to allow one to partake of the meat of a wild beast and fowl cooked in milk, one might think that the prohibition applies only in its most literal context. As a safeguard to prevent this error from occurring, they instituted this prohibition. Therefore, they forbade all meat in milk.

It is permitted to partake of fish and locusts [cooked] in milk.16The Turei Zahav 87:3 and the Siftei Cohen 87:5 mention that there are authorities who forbid eating fish and milk together because it can cause health dangers. They, however, reject that ruling.When a person slaughters a fowl and finds eggs that are completed within it, it is permitted to partake of them together with milk.17This refers to eggs that already have a yolk and whites, but are still connected to the chicken's body (Maggid Mishneh). See the Turei Zahav 87:6 and the Siftei Cohen 87:9 who quote authorities who explain that even though such eggs are considered as meat in certain contexts, there is no prohibition against partaking of them together with milk.

When [milk and meat] are smoked, cooked in the hot springs of Tiberias, or the like, one is not liable for lashes.18Nevertheless, there is a prohibition against partaking of all these mixtures and those mentioned in the following clause. Similarly, when meat is cooked in whey, milk from a dead animal,19I.e., milk that was in the animal's udders when it died or was slaughtered. See Halachah 12. or milk from a male,20The Rama (Yoreh De'ah 87:6) states that, after the fact, there is no prohibition against a mixture of milk from a male and meat. The Siftei Cohen 87:16 explains that this refers to milk from a male human. Even the Rama would forbid milk from a male animal according to Rabbinic Law. or if blood is cooked with milk, one is absolved and is not liable for partaking [of the mixture] because of [the prohibition against partaking of] milk and meat.21Implied is that in the latter instance, one is liable for partaking of blood. The Siftei Cohen 87:15 notes that according to many authorities, one is not liable for lashes for partaking of blood that has been cooked.When, however, a person cooks the meat of a dead animal, forbidden fat, or the like in milk, he is liable for lashes for cooking.22Since we are speaking about meat or fat from a kosher species, the prohibition against cooking applies. In this instance, we do not say that "one prohibition does not fall upon another," because there is no prohibition against cooking a nevelah or forbidden fat. He is not liable for lashes for partaking [of the mixture] because of the prohibition against meat and milk.23He is, however, liable for partaking of a nevelah or of forbidden fat. For the prohibition against [mixtures of] meat and milk does not take effect with regard to [entities] prohibited as nevelah or forbidden fat, because we are not speaking about a more encompassing prohibition, a prohibition which adds a new dimension, or [two] prohibitions that take effect at the same time.24As stated in Chapter 14, Halachah 18, and in Hilchot Issurei Bi'ah 17:8, it is only in these circumstances, that we do not follow the general principle: One prohibition does not fall upon another prohibition.
The commentaries ask: Seemingly, the prohibition against a mixture of meat and milk does add a new dimension to this prohibition, because it is forbidden to benefit from such a mixture. Why then does the prohibition against partaking of milk and meat not apply?
The Rambam attempts to resolve this question in his Commentary to the Mishnah (Keritot 3:4) by explaining that since the prohibition against benefiting from the mixture is an extension of the prohibition against partaking of it, when - as in the present instance - the prohibition against partaking of it does not apply, the prohibition against benefiting from it also does not apply.

When meat falls into milk or milk falls into meat and they are cooked together, the minimum measure [for which one is liable is] enough for one substance to impart its flavor to the other.What is implied? When a piece of meat falls into a bubbling pot26The pot must be boiling hot. If meat falls into cold milk, it will not absorb it. See Halachah 17. full of milk, a gentile should taste [the contents of] the pot.27Chullin 97a states "An Aramean chef shall taste it." Tosafot and others explain that only a chef's word is accepted. He will not lie, because if his falsification is discovered, his professional reputation will be tarnished and he will suffer a loss. We suspect that an ordinary gentile, by contrast, will lie. His word is only accepted with regard to ritual matters when he makes statements in the course of conversation, without knowing that a Jew is depending on his word.
This interpretation is not evident from the Rambam's words. On the contrary, it appears that according to the Rambam, the statements of any gentile are acceptable (see Chapter 15, Law 30, and notes). The Shulchan Aruch (Yoreh De'ah 92:1 quotes the Rambam's words. The Siftei Cohen 92:1 mentions the view of Tosafot. The Rama states that in the Ashkenazic community, the custom is not to rely on the word of a gentile in this context. Instead, we require sixty times the volume of the meat in all instances. Otherwise, both the milk and the meat are forbidden. If it has the flavor of meat, it is forbidden. If not, it is permitted, but the piece of meat is forbidden.28For it certainly absorbed milk.
When does the above apply? When he hurried and removed the piece of meat before it discharged the milk that it absorbed. If he did not remove it [that quickly], we require 60 times its volume,29As will be explained (see Chapter 15, Halachah 6, and notes), our Sages received the tradition that a forbidden substances will not impart its flavor to a mixture when the mixture contains sixty times its volume. because the milk that it absorbed became forbidden. It was discharged and then mixed together with the remainder of the milk.30There is no way of distinguishing the remainder of the milk from the forbidden milk. Hence the entire mixture is forbidden unless there is more than 60 times the amount of the forbidden substance.

When milk falls [onto a piece of] meat [being cooked] in a pot,31As evident from the continuation of the Rambam's words in this and the following halachah, we are speaking of an instance where milk falls on a piece of meat that is not in the sauce. According to Rashi, the lower portion of the meat is resting within the sauce in the pot and its upper portion - on which the milk falls - projects beyond it. According to Rabbenu Yitzchak, the entire portion is outside the sauce. See Turei Zahav 92:2; Siftei Cohen 92:4. (From the Rambam's wording at the beginning of the following halachah, it would appear that he follows Rabbenu Yitzchak's position.) we taste32I.e., we have the meat tasted by a gentile as above. the piece on which the milk fell. If it does not have the flavor of milk, everything is permitted.33I.e., the piece itself is permitted and therefore all the contents of the pot. [More stringent rules apply] if the piece of meat has the flavor of milk. Even though if the piece of meat was pressed to remove [the absorbed liquid], the flavor [of milk] would not remain, since it has the flavor of milk now, it is forbidden and we must measure its entire volume.34Since the meat becomes forbidden, because it is meat that has been mixed with milk, tasting the mixture for milk is not sufficient. Instead, we consider the meat as a forbidden article and measure 60 times its volume. It is not possible to distinguish between the flavor of the forbidden meat and that of the permitted meat. If everything in the pot - the other meat, the vegetables, the sauce, and the spices - is great enough so that the piece is one sixtieth of the entire [volume], that piece of meat is forbidden35Once it becomes forbidden, it is considered as a prohibited entity and cannot become permitted again. Our Sages [Chullin 108b; Rama (Yoreh De'ah 92:3-4)] use the expression: "The piece becomes like carrion," i.e., as if it is inherently forbidden. and the remainder is permitted.36As if it was mixed with 60 times its volume of non-kosher meat. If the entire mixture is not 60 times the volume of the forbidden piece, the entire mixture becomes forbidden.הלכה י

When does the above apply? When he did not stir the pot at the outset when the milk fell into it. [He did so] only at the end37Since he mixed at the end, after the meat became forbidden, the entire mixture may become forbidden. and did not cover the pot.38Thus the piece of meat on which the milk fell remained a discrete entity, separate from the entire mixture. Hence it becomes forbidden.If, however, he stirred the pot from the beginning until the end39The Tur (Yoreh De'ah 82) states that it is sufficient for him to stir the mixture at the beginning. This will cause the milk to be blended throughout the entire mixture. There is no need for him to continue stirring the pot. Rav Yaakov ibn Chaviv maintains that the Rambam would also accept this position. The Rambam mentions stirring the put until the end only for stylistic reasons. This interpretation is also apparent in the Rambam's Commentary to the Mishnah (Chullin 8:3).
In his Kessef Mishneh and Beit Yosef, Rav Yosef Caro differs and maintains that the Rambam's words here should be understood literally. Unless he mixed the pot from the beginning until the end, we fear that it was not mixed well. Hence in his Shulchan Aruch (Yoreh De'ah 92:2, he quotes the Rambam exactly. The Rama, however, cites the Tur's position. or covered [the pot]40For covering the pot also causes the flavor of the milk to be blended throughout the entire mixture. from the time [the milk] fell until the end, [the question of whether a prohibition exists depends] on whether [the milk] imparted its flavor.41And we have a gentile taste the mixture as above.
Similarly, if the milk fell into the sauce or onto all the pieces and it was not known on which piece [the milk] fell,42The Tur and the Rama (Yoreh De'ah 92:2) emphasize that if the person does not stir the pot immediately after the milk fell in, the piece on which the milk fell becomes forbidden. Since its identity is unknown, all the pieces are forbidden unless the entire mixture is 60 times larger than its largest piece.
Rav Yaakov ibn Chaviv and Rav Yosef Caro (in his Kessef Mishneh and Beit Yosef) interpret the Rambam's intent as analogous to that of the Tur. They maintain that the Rambam also would agree that if person waited after the milk fell on the piece, that piece - and perhaps all the pieces - become(s) forbidden.
The Maggid Mishneh offers a different interpretation, explaining that in this instance, we do not say that the piece of meat on which the milk fell becomes forbidden because we do not know which piece it is. Hence rather than have the taste of the milk affect that piece, we stir the entire mixture so that the milk will become blended into it and become nullified as explained in the following note.
The Turei Zahav 92:6 and the Siftei Cohen 92:8 follow the interpretation of the Maggid Mishneh, explaining that in this instance, the principle (Beitzah 4b): "We do not nullify the existence of a forbidden substance at the outset," does not apply. For since the identity of the forbidden substance was never established, there is no specific prohibited substance involved. Hence at the outset, the entire pot is considered as subject to being forbidden. To prevent that from happening, we stir it so that the prohibition will not take effect. he should stir the entire pot so that all its contents will be mixed [thoroughly].43I.e., intentionally mixing the milk throughout the entire pot and thus nullifying its presence. As the Tur (loc. cit) writes, if the milk fell into the sauce, even if the person did not stir the mixture, this would be the ruling. Nevertheless, the Rambam advises the person to stir the mixture so that it will be mixed thoroughly and no trace will remain. If the flavor of milk [can be detected] in the entire pot, it is forbidden. If not, it is permitted. If a gentile to taste [the pot] whom we can rely on cannot be found, we require a measure of sixty whether for meat in milk or milk in meat. If there is one measure in sixty,44More precisely, the permitted substance must be sixty times the volume of the forbidden substance. Thus we are speaking about the forbidden substance being one sixty-first. it is permitted. If there is less than sixty, it is forbidden.

When meat has been cooked in a pot, milk should not be cooked in it.45This applies even on a later day. According to Scriptural Law, after 24 hours, there is no prohibition. Nevertheless, according to Rabbinic Law, at the outset, one should be stringent and not cook milk in a pot in which meat was cooked previously even if it had been cooked several days beforehand. If one cooked [milk] in it, [it is forbidden] if it imparted its flavor.46I.e., it should be tasted by a gentile. According to the Ashkenazic custom not to rely on a gentile, we require that the contents be 60 times the volume of the pot. The Siftei Cohen 93:1 states that it would be very rare for such a situation to exist. Generally, the ratio between a pot and its contents is less than 60. Hence, in most instances, the food would be prohibited.הלכה יב

The udders [of an animal] are forbidden according to Rabbinic Law.47I.e., we are afraid that a certain amount of milk remained in the udder or that the udder absorbed a certain amount of milk. Since we do not know how much milk it absorbed, we assume that it is entirely forbidden. [The prohibition is not of Scriptural origin, because] meat that was cooked in milk from an animal that was slaughtered is not forbidden according to Scriptural Law, as we explained.48Halachah 6.Therefore if one cut it open and discharged the milk it contained, it is permitted to roast it and eat it. If one cut it both horizontally and vertically and then pressed it into a wall until none of the moisture of the milk remained, it may be cooked with other meat.49The ruling regarding roasting is more lenient than the ruling regarding cooking, because when meat is roasted, any fluids it contains are discharged and flow outward without being absorbed (see Halachah 14). When it is cooked, by contrast, it stews in its juices and it and any other meat will absorb the milk it discharges.
The Shulchan Aruch (Yoreh De'ah 90:2) writes that the accepted custom is not to cook it with other meat at all and to cook it alone only after it has been cut vertically and horizontally and pressed into a wall. The Rama adds that it is Ashkenazic custom not to cook it at all.
When an udder has not been cut open, when from a young animal that never nursed50I.e., our Sages enforced their decree universally, without differentiating between one animal and another. or from an older one, it is forbidden to cook it. If one transgressed and cooked it alone, it is permitted to partake of it. If one cooked it with other meat, we require 60 times its volume. The udder itself is calculated in the 60.51In Chapter 15, Halachah 18, the Rambam explains that since only a Rabbinic prohibition is involved, our Sages were more lenient. Thus the Rambam interprets this ruling as being of general significance. The Rashba offers a different rationale for this ruling, explaining that since the meat of the udder is acceptable, we include it in the reckoning of 60. Thus in contrast to other instances where 60 times the amount of the forbidden substance is required, here, we require only 59.

What is implied? If the entire mixture together with the udder was sixty times the volume of the udder, the udder is forbidden,52Rashi, Chullin 97b, explains that we assume that the milk imparted its flavor to the udder. Hence it becomes forbidden as the Rambam proceeds to state. and the remainder is permitted. If there was less than 60 times its volume, the entire mixture is forbidden. Regardless of [the ruling applying to the entire mixture], if the udder fell into another pot, it can cause it to be forbidden. We require 60 times its volume as in the original instance.53Thus according to the Rambam, only 59 times its volume is required. This view is quoted by the Shulchan Aruch (Yoreh De'ah 90:1). The Tur and the Rama differ and maintain that the second mixture is judged more stringently than the first. They follow the rationale of the Rashba cited above. Thus they maintain at first, the udder is included in the reckoning, because its meat is permitted. With regard to the second mixture, by contrast, it is the meat, not the milk of the udder which is forbidden. Hence 60 times its volume is required. [The rationale is that] the udder which is cooked becomes considered as a forbidden piece of meat.We measure [the volume of] the udder at the time that it was cooked, not according to its state when it fell [into the mixture].

We do not roast an udder that has been cut above meat on a spit.54This is a safeguard so that it will not discharge milk which will flow over other pieces of meat. If, however, one roasted it [in that manner], everything is permitted.55For even if its milk does flow over other pieces of meat, they are not forbidden. The rationale is that since it has been cut open, we do not suspect that perhaps some milk remained. Since the entire prohibition is Rabbinic in origin, we are not overly stringent. The Rama states if the udder was not cut open beforehand, the meat that is lower on the spit is forbidden.הלכה טו

It is forbidden to place the skin of a kosher animal's stomach [in milk] to serve as a catalyst for it to harden into cheese. If one used it as a catalyst, [a gentile] should taste the cheese. If it has a taste of meat, it is forbidden. If not, it is permitted. [The rationale is that] the catalyst is itself a permitted entity,58Hence the logic mentioned in the following note does not apply. for it comes from the stomach of a kosher animal. [The only question] is [whether] the prohibition against meat and milk [was violated] and that is dependent on whether the flavor was imparted.[Different laws apply, however, when] one uses the skin of the stomach of a nevelah, a trefe, or a non-kosher animal. [The rationale is that] since the catalyst is forbidden in its own right, the cheese becomes forbidden, not because of the prohibition of meat and milk, but because of the prohibition against a nevelah. For this reason, [our Sages] forbade cheeses made by gentiles, as we explained.59Chapter 3, Halachah 13. As the Rambam states in that halachah, since the amount of skin used is minimal, we might think that no prohibition is involved, for the forbidden substance would be nullified. Nevertheless, the Rabbis ruled stringently, explaining that since the catalyst which causes the milk to curdle is forbidden, everything is forbidden.

Meat alone is permitted and milk alone is permitted. It is [only] when the two become mixed together through cooking that they both become forbidden.When does the above apply? When they were cooked together, when a hot object fell into a hot object,60For in this instance, the two substances will be absorbed by each other just as if they had been cooked together. or when a cold object fell into a hot object.61For we follow the principle (Pesachim 76a): "The lower one dominates," and the food is considered as hot. If, however, [milk or meat] that is hot fell into the other when it is cold, [all that is necessary is to] remove the surface of the meat which touched the milk; the remainder may be eaten.62We assume that the meat's surface absorbed a small amount of milk while it was cooling down (ibid.). Hence the surface is forbidden and must be removed. The milk does not, however, permeate beyond the surface. Therefore the remainder is permitted. With regard to the milk, it appears that there is no prohibition. The Radbaz explains that since it is not possible to remove the surface of the milk, there is no prohibition whatsoever. Other Rishonim require that the milk be sixty times the volume of the surface of the meat. The Shulchan Aruch (Yoreh De'ah 91:4) quotes the Rambam's ruling and the Siftei Cohen 91:8 states that this decision is accepted by the Rama despite the fact that this might appear incompatible with some of the other rulings of the Rama. The Turei Zahav 91:7, however, argues in favor of the view of the other Rishonim.
If cold [meat] fell into cold [milk or the opposite], one must wash the piece of meat thoroughly.63Since they are both cold, there is no suspicion that one will be absorbed by the other. Washing the meat is necessary only to remove any traces of milk that might be left. [Afterwards,] it may be eaten. For this reason, it is permitted to [carry] meat and milk bound together in a single handkerchief, provided they do not touch each other. If they do touch each other, one must wash the meat and wash the cheese.64The Bayit Chadash rules that this applies only when one of them is moist. If they are both solid, they need not even be washed. [Afterwards,] he may partake of them.

When a substance is salted to the extent that it cannot be eaten because of its salt,65In previous eras, before the advent of refrigeration, meat was salted thoroughly to preserve it. Afterwards, when one desired to partake of it, he would soak it in water to remove the salt (Rashi, Chullin 112a). The Radbaz states that we are speaking about salting meat in a manner similar to the way it is salted to remove its blood. If less salt than that is used, these laws do not apply. See the Shulchan Aruch (Yoreh De'ah 91:5) which discusses these laws. is considered as if it is boiling.66I.e., we assume that it will cause substances to be discharged and absorbed as cooking does. This is merely a Rabbinic stringency.It must be emphasized that the comparison to cooking is not total. Generally, salting only causes the surface of the substance to become forbidden. If, however, the substance is fatty, the entire substance becomes forbidden (ibid.:6). If it can be eaten in its present state like kutach,67A mixture of milk, breadcrumbs, salt, and spices, commonly served as a dip in Babylon. it is not considered as if it is boiling.68All that is necessary is to wash the meat and/or cheese thoroughly.

[The following rules apply when] a fowl that has been slaughtered falls into milk or kutach that contains milk: If it is raw, it need only be washed thoroughly and it is permitted. If it was roasted, one should remove its surface.69There is a difference of opinion among the Rabbis if this is speaking about a roasted fowl that is hot, or even one that is not hot. According to the latter opinion, it will still absorb some milk because it has become soft and permeable. The Shulchan Aruch (Yoreh De'ah 91:7) quotes the first view while the Turand the Rama mention the second. If it has portions where it is open70I.e., instead of being a solid surface, the surface of the meat cracks open in several places. or it is spiced and it falls into milk or kutach, it is forbidden.71Because the cracks in its surface or the spices will cause it to absorb the milk to a greater extent than it would otherwise. This clause appears also to be referring to meat that has been roasted. There are, however, opinions that interpret it as referring to raw meat. See Siftei Cohen 91:21.הלכה כ

It is forbidden to serve fowl72Needless to say, this applies to meat (see Lechem Mishneh). together with milk on the table upon which one is eating.73They may, however, be placed together on a serving table (Chullin 104b). This is a decree [enacted] because habit [might lead] to sin.74Since both substances are permitted and they are served together, one might accidentally partake of them together.Implied is that if substances are forbidden and one would not ordinarily partake of them, there is no difficulty in having them served on the table at which one is eating. See Siftei Cohen 88:2. We fear that one will eat one with the other. [This applies] even though fowl with milk is forbidden only because of Rabbinic decree.75See the Shulchan Aruch (Yoreh De'ah 88:2) which explains that if a distinction is made, e.g., the milk is placed on one type of placemat and the meat on another, there is no prohibition.

When a loaf has been baked together with roasted meat, or fish were roasted together with meat,81Even if they did not touch each other. Note the Shulchan Aruch (Yoreh De'ah 116) and the Turei Zahav 95:3) which mention that there is a prohibition against eating fish roasted with meat because it could cause a health problem. it is forbidden to eat them together with milk.82For the vapors from the meat become absorbed in the bread or in the fish. In Chapter 15, Halachah 32, the Rambam rules that vapors do not cause an object to become forbidden. There is not necessarily a contradiction between these two rulings, for here we are speaking about a small oven [Radbaz, Shulchan Aruch (Yoreh De'ah 97:3). Even though, after the fact, kosher meat roasted together with non-kosher meat in a small oven is permitted, here one is not deeming the bread or fish forbidden, one is merely prohibiting that it be eaten with milk (Siftei Cohen 97:4). When meat was eaten83Or cooked [Radbaz, Shulchan Aruch (Yoreh De'ah 95:1)]. The Shulchan Aruch adds that this ruling applies only when the dish was thoroughly washed and no trace of meat remains. in a dish and then fish were cooked in it, it is permitted to eat those fish together with kutach.84Even though the kutach contains milk. The rationale is that although the flavor of the meat was imparted to the dish and from the dish, it was imparted to the fish. Nevertheless, since it went through these two intermediate stages, it is not considered significant and does not cause the fish to be considered fleishig. The Rabbis referred to this concept as nat bar nat - notain taam bar notain tam ("imparting merely flavor a second time").It must be emphasized that nat bar nat is permitted only with regard to a mixture of milk and meat. The rationale is that both milk and meat are permitted, a prohibition only exists when they are mixed together and if one of them has been weakened to the extent that it is nat bar nat, it is not considered significant. When, however, an entity is inherently forbidden, e.g., non-kosher meat, when its flavor becomes absorbed into a dish, that dish becomes forbidden and it may not be used again for hot food (Radbaz).

When a knife was used to cut roasted meat85The Rambam's wording implies that the meat was hot (Radbaz). This ruling applies also to hot cooked meat (Kessef Mishneh). There are opinions that maintain that this ruling also applies when the meat was cold (Radbaz). and then was used to cut radish or other sharp foods, it is forbidden to eat them together with kutach.86Rashi, Chullin 111b, states that the rationale is that it is likely that there will be a small amount of fat left on the knife. Thus when the knife is used to cut the sharp food, its sharpness will cause that the flavor of the fat will be imparted to it. According to this view, if the knife was cleaned or used to cut another substance first, it does not cause the radish to be forbidden [Shulchan Aruch (Yoreh De'ah 96:5); note also the dissenting view of the Rama]. (This opinion speaks of fat being left on the knife, for if there was no fat there, seemingly, this instance would resemble the concept of nat bar nat mentioned in the previous halachah.)There are, however, other opinions (Tosafot, Sefer HaTerumot) which maintain that this ruling would apply even if the knife was clean. The rationale is the pungency of the food and the pressure of the knife cause it to absorb more than an ordinary instance of nat bar nat.
From the Rambam's wording, it appears that the entire radish is forbidden. The Shulchan Aruch (Yoreh De'ah 96:1), however, rules that it is sufficient to remove a piece a fingerbreadth in thickness. The Rama, however, mentions the Rambam's view. If, however, one cut meat [with a knife] and afterwards cut zucchini or watermelon,87I.e., substances that are not pungent and soft and contain moisture. If one cuts a vegetable that is not soft and moist, it is sufficient to wash it [Shulchan Aruch (Yoreh De'ah 96:5)]. one should scrape away the place where the cut was made and the remainder may be eaten with milk.

We do not place a jar of salt near a jar of kutach, because it will draw out its flavor.88The Ra'avad and the Radbaz note that the Rambam apparently had a slightly different version of Chullin 112a, the source for this halachah, than that found in the standard printed texts of the Talmud. According to the standard version, the rationale is that we fear that some drops of kutach will fall into the salt. The Radbaz adds that according to the Rambam, the prohibition applies only with regard to earthenware jugs. If they are made from metal, the material will be too dense to allow for the flavor to be drawn out. Thus one will cook meat with this salt that has the flavor of milk. One may, however, place a jar of vinegar near a jar of kutach, because the vinegar will not draw out its flavor.89According to the other rationale, the kutach will remain a distinct entity if it falls into the salt, but it will become mixed with the vinegar and nullified if it falls into it (Radbaz; Turei Zahav 95:16).הלכה כו

When does the above apply? With regard to the meat of a domesticated animal or a wild beast.93The requirement of this stringency for the meat of a domesticated animal is understandable, for the prohibition is of Scriptural origin. Nevertheless, according to the standard text of Halachah 4, the prohibition against a mixture of milk and the meat of a wild beast is also Rabbinic in origin. What then is the difference between the meat of a wild beast and that of a fowl? The Kessef Mishneh, however, explains that the meat of a domesticated animal resembles the meat of a wild beast. Hence it was necessary for the Rabbis to forbid it. Alternatively, Rabbenu Tam explains that the meat of a wild beast will stick to a person's mouth and hands more than the meat of a fowl. If, however, one [desires to] eat the meat of a fowl after eating cheese or milk, it is not necessary for him to clean his mouth or wash his hands.94Since only a Rabbinic prohibition is involved, our Sages did not enforce any further stringency.הלכה כח
