BTW, I fry the stuff in slices about a half inch thick using a lot of oil, but bacon grease is best. It was one of those by-products of butchering hogs and indeed eaten by poor folks, but nowadays they give prizes for the best at state fairs just like they do with jerky or trail baloney.
Nowadays we have it only as a treat becasue the stuff when cooked is cholesterol hell!!!! My kids refer to it as "Pig Lips" because that's one of the things ground up in it........I never mention to most folks that they grind up the assholes too..........
