So, I went to my neighborhood greek grocery... well, one of them (I live in Astoria, NY, so-called largest population of Greek folk outside of Athens), in search of Feta cheese knowing fullwell that I know just about nothing about it aside from its yummy. So I tell the guy 'sharp' and he gives me something and its wonderful, but what about all those other kinds?? and whats the difference? and what are its uses aside from cut-off-put-in-mouth? Anyone feeling like giving me a Feta lesson?
