Spare ribs cook times by temperature
Ribs are timed per rack, not per pound. Schedule on the long end; go by internal temperature.
| Pit temp | Rate | Cook time |
|---|---|---|
| 225°F | per rack | 5 h 30 min to 6 h |
| 250°F | per rack | 4 h 30 min to 5 h |
| 275°F | per rack | 4 h to 4 h 30 min |
Done: bend test: the rack cracks on the surface, about 195-203°F between the bones. Rest 10 minutes.
