Beef shank is a cut of meat taken from the leg of a cow, specifically from the area around the knee and ankle. It is known for its rich flavor and is often used in slow-cooking methods like braising or stewing. The meat is tough due to the muscle's frequent use, but it becomes tender and flavorful when cooked slowly, allowing the connective tissues to break down. This cut is typically sold with the bone in, which adds depth to soups and stocks. Beef shank is commonly used in dishes like osso buco, a traditional Italian recipe, and is a popular choice for hearty winter meals.
