Flank vs Heart — What's the Difference?
Quick Answer
Side-by-side
| flank | heart | |
|---|---|---|
| Primal | flank | offal |
| Muscle / location | abdominal flank steak | Chest cavity — between the lungs, behind the brisket |
| Character | Long, fibrous abdominal cut; benefits from slicing across the grain. | A dense, muscular organ with a mild, beefy flavour — closer to lean muscle meat than most offal. Often grilled on skewers (anticuchos in Peru) or braised. Very lean; benefits from marination. Widely eaten in Latin America, Eastern Europe, and across Asia. |
Key differences
- Different primals: flank 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.
When to use each
Flank
Pick Flank when you want its specific marbling/texture profile: Long, fibrous abdominal cut; benefits from slicing across the grain.

Pick Heart when its primal/muscle traits fit the dish: A dense, muscular organ with a mild, beefy flavour — closer to lean muscle meat than most offal. Often grilled on skewers (anticuchos in Peru) or braised. Very lean; benefits from marination. Widely eaten in Latin America, Eastern Europe, and across Asia.
