Start your lamb up higher, over a low-medium heat. (Use ash to control the temperature and this also helps the charcoal last longer)
Keep the lamb up high for 2 hours. We want to slow cook the lamb as much as possible. Larger chunks of meat need longer cooking time to ensure it is cooked and not just dark on the outside.
Once the internal temperature reaches 60 - 65 degrees, drop the lamb closer to the charcoal.
When you want to intensify the heat and brown up your lamb even further, scratch up the charcoal. This will provide more airflow and allow for a stronger burn.
Once the lamb has reached your desired cooking temperature, remove from the rotisserie.
Wrap your lamb in foil and allow to rest for 10-15 minutes.
Apply lemon to your lamb, serve and enjoy!
