Stuffed beef casing, also known as DERMA (5 letters), is a type of sausage made from beef that is stuffed into a natural or artificial casing. The beef is usually ground and mixed with spices and other ingredients before being stuffed into the casing. The casing helps to hold the shape of the sausage and also helps to keep the flavor and moisture inside. DERMA is a popular ingredient in many dishes, such as stews, soups, and casseroles.
