A pig's stomach, commonly stuffed with a sausage mixture, simmered until done, then baked until brown. It's usually available only by special order and should be stored in the refrigerator for no more than 2 days. Before using, the stomach should be cleaned of all membrane, rinsed thoroughly, then patted dry.
