A beef tail, also known as oxtail, is the tail part of a cow. This piece of meat is often used in the kitchen because of its rich flavor and firm texture. The beef tail consists of bones, cartilage, and meat, and contains a significant amount of collagen, which, when cooked slowly, yields a gelatinous and flavorful broth or stew. Traditionally, beef tail is used in dishes such as oxtail soup or stews, where it is slowly braised to fully release the flavors and make the meat tender.
