I don't know whether you roasted the whole leg of lamb or the roast leg of lamb, but whether it is the whole roast or the roast block, you should marinate it before roasting. You need to add salt, monosodium glutamate, cumin noodles, onions, garlic, sugar and cooking wine, and then prepare some cumin noodles and Chili noodles for later use. Roasting the whole lamb leg needs to be more than 500mm away from the charcoal fire, and it takes about half an hour to 1 half an hour according to the size of the lamb leg, so the barbecue doesn't take that long. It's cumin noodles that bake quickly. Put pepper noodles after baking. Be sure to put Chili noodles before the exam. Pepper tastes bitter when roasted.
