Mom used to make gulyásleves with all kinds of things in it. We would all be served then spend about 3 mn saying Hey, who wants my kidneys? I've got some carrots to trade! Nowadays she doesn't put kidneys in it, and it just doesn't taste the same. I learned to love tongue at her table, too. Pig's feet never sent me, she likes all that gristle, I don't. And I don't eat the gall bladder in formaldehyde, I just keep in on my spice shelf pour épater les bourgeouis. I make my gravy with all the parts, I just mince them up. I remember being told by my then-spouse to not include the kidneys, so I minced them finer. He had a total kidney failure once for no reason, so we wondered if it was the rabbit's revenge, as that was who's kidneys I'd been feeding him...

And check out the Larousse Gastronomique, the Encyclopedia of Food edited by the French. Under "offal" it has pages and pages and PAGES of recipes for things Americans tend to think of as inedible! But then you look under "leftovers" and find this simple definition: The product of poor planning in the kitchen. I kid you not! And not a single recipe for hash, or anything else I do with leftovers all the time!

De gustibus disputandum non est, indeed...
