Buttermilk...yuck. Never could stand that either but I was never made to put it down as a kid. Buttermilk biscuits or pancakes are fine, but I can't drink it. *shudder*
As far as cheeses go, you're not supposed to put cottage cheese in lasagna. That's just a shortcut for lack of ricotta. Supposed to be a blend of cheeses too. Not just mozzarella. For pizza topping a blend of at least 3, but 5 or better is preferred.
Aw crap...I just read what I wrote. I sound like some sort of friggin' arm chair Martha Stewart or something.
