| Character | The tail, cut into thick cross-sections exposing a central bone surrounded by rich, gelatinous meat. One of the most universally recognized cuts across all cultures. Ideal for slow braising — produces extraordinarily rich, collagen-heavy broth. | Also called the knuckle. A lean, moderately tender cut from the front of the round, near the sirloin. Used for roasts, kabobs, and stir-fry. Not from the sirloin despite the name. |
