Side-by-side
| eye of round | tendon | |
|---|---|---|
| Primal | round | offal |
| Muscle / location | Small oval muscle within the outside round | Connective tissue at joints — particularly the hock/lower leg |
| Character | A small, tight-grained, very lean oval muscle embedded in the outside round. Uniform shape makes it ideal for roasting and slicing thin (roast beef deli meat). Can be tough if overcooked. | 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. |
Key differences
- Different primals: round vs offal.
- Texture and slicing: compare fibrous, grain-heavy cuts vs more tender steak-style muscles based on each cut’s description.
- Retail naming diverges by country—always map through a canonical cut when translating menus or labels.
