Haslet (locally pronounced "hacelet") is a herbed pork meat loaf (or is sometimes prepared as a sausage). In Wales, it's pig liver cooked with onions and potatoes! Haslet comes from the old French word for entrails, but it essentially refers to the ingredients being very finely minced.
Haslet is made from nose, tail, teats, hooves, lips, anal parts and eyes, all bellonging to the pig.
