Depending on the size of your lamb you may wish to adjust your quantities of the mustard, lemons, onion, garlic and thyme inside the lamb.The lamb that I cooked in my video was 17kg and I finished cooking it in around 7 hours.Once the lamb reached an internal temperature of 80 degrees Celsius I started cutting and serving.The basting I always have on hand infusing over time to be stronger. It is not included in the nutritional information as you will only use what you need and keep the rest.
