|"How many slices did you want?"|
Over at NPR, they have a piece about the "variety meats" known as offal. (It's pronounced "awful", BTW.)
Offal can take many forms: lamb kidneys, pig brains, cow faces, duck hearts, cow tongues, that sort of thing. The example above is terrine: "crunchy pig's ear encased in gelatin."
Like I said, it's pronounced "awful." Although I must add, if you're going to kill an animal, I guess it makes sense to eat every last bit of it. Even the testicles!)
