At the very bottom of daf TB Khullin 103b we begin eighth chapter of our massekhet. This chapter deals with the laws of mixing milk and meat together. Because the verse “you shall not cook a kid in its mother’s milk–לֹֽא־תְבַשֵּׁ֥ל גְּדִ֖י בַּחֲלֵ֥ב אִמּֽוֹ” appears three times in the Torah, the rabbis derive three Torah prohibitions. One is not permitted to cook milk and red meat together. One is not permitted to eat milk and meat together that has been cooked together. One is not permitted to derive any benefit from a mixture of milk and meat together, for example, giving a milk and meat mixture to your pet dog.
The Mishnah begins
“It is prohibited to cook any meat of domesticated in milk, except
for the meat of fish and grasshoppers, whose halakhic status is not that of
meat.” (Sefaria.org translation) The Gemara discusses whether chicken and
undomesticated animals are included in this Torah prohibition or is the mixture
only prohibited according to rabbinic law. Although the Gemara doesn’t come to
a conclusive answer today, the final consensus is that mixing milk and chicken
is only prohibited by rabbinic law. This has practical implications we shall
learn later. If there is a doubt when red meat and milk has been accidentally mixed
together in a proportion more than 60:1 (for example, some milk fell into a
beef stew), the entire mixture must be thrown away. We are always stringent
when comes to not transgressing a Torah prohibition. If there’s a doubt
concerning an accidental mixture of chicken and milk, one need not throw out the
mixture because we may act leniently in a case of a rabbinic prohibition.
If the
prohibition of mixing chicken and milk together is a Torah prohibition then all
three above prohibitions apply. If the prohibition of mixing chicken milk
together is only a rabbinic prohibition, do all three prohibition apply? I was
surprised to learn that no. Both Rambam and the Shulkhan Arukh both poskin that one is only forbidden to eat
chicken and milk together.
“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. 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. Therefore, they forbade all meat in milk.” (Mishneh Torah Forbidden Foods 9:4)
“The prohibition of the mixture
applies only to that of meat and milk from a pure animal: if one of the two
comes from an impure animal, cooking as well as enjoyment is permitted. Cooking
and enjoyment are permitted if the meat comes from a wild animal or poultry,
even if both the meat and milk come from pure animals. Such a mixture is even
prohibited to eat only by rabbinic ordinance. Whereas the flesh of fish and
locusts is not even prohibited by rabbinic ordinance.
GLOSS: It is customary to put poultry meat in almond milk, seeing that such a
mixture, even if the milk were real, is only prohibited by rabbinic order; but
when it comes to beef, a few almonds must be left in the milk to avoid
suspicion, as stated earlier, § 66, regarding blood.” (Shulkhan Arukh, Yoreh De’ah 87:3) Today where plant-based milk’s are very
common, one need not suspect an observant Jew violating the Rama’s custom when a glass of plant-based
milk is on the table without some kind of the container on the table
The second
Mishnah teaches another important halakha.
One may not place chicken and milk on the same dining room table lest people
unthinkingly eat them together. However, one may place chicken and milk
together on the kitchen countertop because nobody usually eats from that countertop.
“The meat of birds may be placed with cheese on one table but
may not be eaten together with it; this is the statement of Beit
Shammai. And Beit Hillel say: It may neither be placed on one table nor
be eaten with cheese. Rabbi Yosei said: This is one of the
disputes involving leniencies of Beit Shammai and stringencies of Beit
Hillel. The mishna elaborates: With regard to which table are these halakhot
stated? It is with regard to a table upon which one eats. But on a
table upon which one prepares the cooked food, one may place this
meat alongside that cheese or vice versa, and need not be
concerned that perhaps they will be mixed and one will come to eat them
together.” (Sefaria.org translation) Our Mishnah records one of the six times
when Beit Shammai is more stringent
than Beit Hillel and as usual we follow the opinion of Beit Hillel.
