I've got a "grease tooth" so I like bisquits/gravy, and SOS. i have always loved kieshka blood sausage - the kind with barley in it, cold, with black pumpernickle bread - also very greasy.
I REALLY can't stand liver, i actually gag. I don't like heart (like deer heart) either because it has a livery taste/texture that reminds me of liver and makes me want to puke just as much as liver due to my conditioning. Ughh.
