| flap steak | hanger | |
|---|---|---|
| Primal | sirloin | plate |
| Muscle / location | Bottom sirloin, obliquus internus abdominis muscle | Hangs from the diaphragm, between the last rib and the loin |
| Character | A thin, coarse-grained steak from the bottom sirloin. The American name for what the French call bavette d'aloyau. Open grain absorbs marinades extremely well. Popular for fajitas, stir-fry, and carne asada. Often confused with skirt steak but from a different location entirely. | Also called hanging tender or butcher's steak. A thick, V-shaped muscle that 'hangs' from the diaphragm — only one per animal. Extremely flavorful with a coarse grain. Distinct from skirt steak, which is the diaphragm muscle itself. |
