It's all about preparation. I don't think I could eat certain organs without puking just from the thought/looks. You couldn't get me to eat heart for example. I've tried to but couldn't get over it (chicken hearts actually). And even liver, I'm not sure I'd eat.

German Liver Sausage? That is one of the most delicious things on earth!

How's this for a "recipe": Beef trim (50%), beef liver (20%), beef heart (15%), and beef kidney (15%).

Take a nice piece of rye bread (best is a real sourdough rye bread), spread the Leberwurst very thick, top off with a cornichon and/or pickled mini onion. Heavenly.

I've tried chicken hearts on a skewer at Japanese restaurants a few times, and of all the organs I think it's the least organ-y. It's a working muscle and pretty much tastes like it.
