Butcher's Discard is a term used to describe the parts of an animal that are not typically used for food. This includes FAT and OFFAL, which are the two crossword solutions. FAT is the layer of tissue found beneath the skin of an animal, while OFFAL is the internal organs and entrails of an animal. Both FAT and OFFAL are considered by-products of the butchering process and are often discarded or used for other purposes.
