I apologize in advance.
I know this is going to sound silly. I know that someone will undoubtedly say "Russians have many kinds of cheese," or "This is like asking what color scarf Russians wear." Here's the crazy question: what kind of cheese is the general kind found in Russian stores? There was one kind in particular that you typically find in stores. It was just a white, mild tasting cheese, and not being a cheese nut, I don't know what the actual name is for it in the US.
