Side-by-side
| brisket flat | chuck eye steak | |
|---|---|---|
| Primal | brisket | chuck |
| Muscle / location | Deep pectoral muscle — the lean, flat portion of the brisket | 5th rib, where the chuck meets the rib primal |
| 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. | The 'poor man's ribeye' — cut from the 5th rib, right where the chuck primal ends and the rib primal begins. Contains the same longissimus dorsi muscle as a ribeye but from a less premium section. Similar marbling at a significantly lower price point. Only 2 steaks per animal from this location. |
