The udder of a kosher animal presents a complex halachic case. Although it is classified as meat, it contains milk, raising important questions regarding the prohibition of Basar Bechalav. While it may be permitted after proper removal of the milk in accordance with halachic guidelines, differing opinions, customs, and distinctions between Biblical and Rabbinic prohibitions make the practical laws intricate and nuanced. This Shiur covers Shulchan Aruch, Yoreh De’ah, Basar Bechalav: Siman 89, Se’if 4—using a meat knife to cut cheese—and Siman 90, Se’ifim 1–4, discussing the udder of a kosher animal. Timestamp:
