What's Really Cheese? - Keeping it Kosher Clip

I'm from Montreal. There's European influence. Sure. And so I know that the French tend to make fun  of the things that we call cheese. Not everything   that we call cheese is really cheese.  In terms of the halacha and categorizing   things that are cheese, what is actually  cheese in halacha, and what's not cheese? Oh, that's a big machloket. Rennet-set  cheese, cheese that either has rennet,   real calf rennet in it, cheese that has  an enzyme in it, a rennet type of enzyme   to make the cheese. That's definitely  gevina. That has the halachos of cheese. So, mozzarella, cheddar... 100%, those are all subject to the  halachic stringencies of cheese. However,   acid-set cheese is a machloket. Rav  Moshe Feinstein has a safek, himself,   whether or not acid-set cheese requires  a mashgiach. There are different opinions   about that. But rennet-set cheese is  definitely cheese whether the rennet is   some synthetic rennet or whether it's coming  from a calf, whatever it is, that is cheese.
