This text explains that you can´t cook a kid, specifically a goat in it´s mothers milk. This same phrase is shown twice more in the Torah.
This commentary explains that one time in the Torah the sentance is prohibiting eating meat and milk, once cooking it, and once gaining benefit from it.
This says that the pasuk is not just referring to boiling with water, but also meat in milk. Reish Lakish actually gets this from a different phrase, so the Torah talks about meat and milk more than those three times.
According to Rabbi Yosef Karo, author of the Shulchan Aruch,the rule on meat and milk is talking about any domesticated animal, not just a goat. He was a Rishon.
This piece of the Mishneh Torah written by Rambam, a rabbi from the time of the Rishonim teaches that you can get benefit from meat and milk if one of the pieces (meat or milk), is impure. I was wondering what pure meant.
Rabbi Yosef Karo preaches that pure means kosher, and you can benefit from a wild animal in milk. There are specific rules about non dairy milk having a Heker. The piece in italics comes from the Rem"a (in the Mapah), while the Rest is Rabbi Yosef Karo.
Using An Oven For Both Meat & Dairy
By Rabbi Dovid Heber
If a pan with meat and a pan with dairy are covered, one may place both of them in an oven l’chatchila. This is true, provided that the pans do not touch each other and do not touch the “opposite” food (e.g., a meat pan may not rest on a rack with dairy residue).
If only one pan is covered and is on the lower shelf, it is also muttar l’chatchila. An uncovered meat pan that contains liquid may not be placed below a dairy pan in the oven (even if the top pan is covered).
It is prohibited for one to bake milk and meat products uncovered at the same time in an oven. B’dieved, if one erred and baked dairy food and a meat product in the oven at the same time (in different pans), the following halachos apply:
- If both the milk and meat dishes were uncovered, and they were not liquidy and not charif (sharp), everything is b’dieved kosher. If either the pan with meat or the pan with dairy is liquidy or sharp (and they are both uncovered), the oven and all the food in the oven may be treif and the keilim (vessels) used with these dishes may require kashering.
- If two pans touch, the following applies: If a pan with meat touched a pan with dairy in the oven (and there was no residue on the outside of either one), the food and keilim are b’dieved kosher.
- If a meat oven is clean, one may bake a dry, uncovered (or covered) dairy item in it. It is not necessary to first kasher the oven or wait 24 hours. If one wants to bake a dry, uncovered dairy item immediately after cooking meat, one should first wait for the oven (which must be clean) to cool down.
An Achron, Rabbi Dovid Heber from Star K, talks about cooking meat and milk in the same oven. He says that you need to cover the pans to block the smell from spreading. He gives real life examples of what to do in different situations.
