Philadelphia’s scrapple is made of offal, which includes the skin, organs, feet, and head of a pig after butchering it for the prime cuts, according to Sand & Succotash. To make Philadelphia’s scrapple, simmer the offal until tender, strain it, season it, and add it back to the broth thickened with cornmeal. The cornmeal binds the sausage into a porridge, which is poured into a loaf pan, and, once it is cooled, can be sliced and fried.
