|---|---|---|
| Primal | brisket | chuck |
| Muscle / location | Deep pectoral muscle — the lean, flat portion of the brisket | Teres major muscle, tucked alongside the shoulder blade |
| Character | The leaner half of the whole brisket. Uniform rectangular shape makes it ideal for even slicing. The competition BBQ cut — prized for its presentation. Also the traditional cut for corned beef and pastrami. Less forgiving than the point — requires precise temperature control to avoid drying out. | A small, narrow muscle from the shoulder that resembles a miniature tenderloin in shape and tenderness. Only about 250-350g per side, making it one of the lowest-yield cuts on the animal. Extremely tender but relatively unknown outside professional kitchens. |
