Yosef Karo

“ Paragraph 3 — It applies only with regard to the meat of a pure domesticated animal in the milk of a pure domesticated animal, but meat of a pure animal in milk of an impure animal or meat of an impure animal in milk of a pure animal, are permitted in boiling and in benefit. And meat of a wild animal or fowl, even in the milk of a pure animal, is permissible to boil and have benefit from. ”

“ And furthermore, the container that is used to make shampoo should not be used [for anything else] because the ashes on the stove that are used to make shampoo are mixed with milk and meat. Therefore it is forbidden to use the pots that are usually on the stoves in the winter lodges because sometimes milk and meat splash on them from the cooking going on in the oven itself. After the fact, we do not worry about the above laws, and furthermore even initially they are only a chumra b’alma (stringency of the world) . One who is lenient will not lose. ”

“ One who cooks an embryo in milk is liable, and one who eats them cooked together is liable. But cooking the placenta, skin, tendons, bones, ikari karnaim (The part of the horn that is found below the skin) ,or soft hooves [in milk] is exempt [from the Torah] and one who eats them is exempt. ”
