Beef tongue, also known as ox tongue, is a type of beef cut that comes from the tongue muscle of a cow. It is a muscle that is well-exercised, which gives it a firm texture, and is high in collagen, which makes it ideal for slow cooking.

Beef tongue is a delicacy in many cuisines around the world and is known for its rich and beefy flavor. It can be prepared in many ways, including boiled, roasted, grilled, or braised. The outer layer of skin on the tongue needs to be removed before cooking.
