Not any one favorite. Cheek and tongue are quite good, ribs are good, hearts are good. Lungs rather depend on how much a person smoked, of course, and liver on how much they drank. Guts are mostly there for sausage casings.

You probably don't want to know the details, really. It would be a shame for you to have nightmares about being in a meat grinder or some such thing, hmm?
