|---|---|---|
| Primal | round | offal |
| Muscle / location | Roast from the outside round / bottom round | Connective tissue at joints — particularly the hock/lower leg |
| Character | A lean, economical roast from the outer thigh. The classic American pot roast cut — braised low and slow with vegetables. Also used for deli roast beef when oven-roasted and sliced paper-thin. Tougher than inside round but more affordable. | Collagen-rich connective tissue extracted from the leg joints, particularly the Achilles tendon area. Extremely gelatinous when slow-cooked; provides body and sticky texture to braises and soups. Prized in Korean, Vietnamese, and South Asian cuisine for its chew and the richness it adds to broth. |
