Scrapple is a savory mush in which cornmeal and flour, often buckwheat flour, are simmered with pork scraps and trimmings, then formed into a loaf. Small scraps of meat left over from butchering, too small to be used or sold elsewhere, were made into scrapple to avoid waste. Scrapple is best known as a regional food of Philadelphia, New Jersey, Delaware, and Maryland.
Scrapple is typically made of hog offal, such as the head, heart, liver, and other scraps, which are boiled with any bones attached (often the entire head), to make a broth. Once cooked, bones and fat are discarded, the meat is reserved, and (dry) cornmeal is boiled in the broth to make a mush. The meat, finely minced, is returned, and seasonings, typically sage, thyme, savory, and others are added. The mush is cast into loaves and allowed to cool thoroughly until gelled. The proportions and seasoning are very much a matter of the region and the cook's taste.
