Offal , also called, especially in the United States, variety meats or organ meats, refers to the internal organs and entrails of a butchered animal. The word does not refer to a particular list of edible organs, which varies by culture and region, but includes most internal organs other than muscle and bone. As an English mass noun, the term "offal" has no plural form. Some cultures shy away from offal as food, while others use it as everyday food, or in delicacies.
