|---|---|
| Rare | 49-51°C (120-125°F) |
| Medium-Rare | 54-57°C (130-135°F) |

Whole muscle cuts of beef are safe at 63°C (145°F) with a 3-minute rest, according to food safety authorities. Use a calibrated meat thermometer in the thickest part, away from bone.
Position the tenderloin side away from direct heat — it cooks faster than the strip side.
Temperature accuracy matters more than timing. Factors like wind, ambient temperature, grill type, and meat thickness all affect cook times. Always verify doneness with a thermometer rather than relying solely on the clock. — AmazingRibs.com
