Step-by-Step: Rack of Lamb at 220°C
- Preheat: Get your BBQ to a stable 220°C (425°F). Use a grill thermometer at grate level for accuracy.
- Prep: Bring the rack of lamb to room temperature (15-20 minutes). Pat dry and season generously.
- Set up: Configure your BBQ for direct then indirect heat. Place coals on one side only, or turn off one burner on a gas BBQ.
- Cook: Place the rack of lamb on the grate and cook for 15-20 minutes. Flip halfway through.
- Check: Use a digital meat thermometer. Target: 54-57°C (130-135°F) for medium-rare.
- Rest: Remove from heat and rest before cutting or serving.
Common Mistakes at 220°C
- Not preheating properly — a cold grill at 220°C means uneven cooking and longer times.
- Skipping the thermometer — time is a guide, internal temperature is the law.
- Opening the lid too often — every peek drops the temperature by 10-15°C and extends cooking time.
- Not resting — cutting immediately loses up to 30% of the juices. Rest for at least 5 minutes.
