Scrapple (Pennsylvania Dutch) is traditionally a mush of pork scraps and trimmings combined with cornmeal and flour, often buckwheat flour, and spices. It is similar to pon haus, which uses only the broth from cooked meat. The mush is formed into a semi-solid congealed loaf, and slices of the scrapple are then panfried before serving. Scraps of meat left over from butchering, not used or sold elsewhere, were made into scrapple to avoid waste.
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 to the pot and seasonings, typically sage, thyme, savory, black pepper, and others, are added. The mush is formed into loaves and allowed to cool thoroughly until set. The proportions and seasoning are very much a matter of the region and the cook's taste.
