In fact, there are many ways to stew trotters soup. Besides lettuce, you can also stew pig's trotters with peanuts and soybeans. The method of stewing pig's trotters with lettuce is very simple. When the oil pan is hot, slice ginger, onion and star anise, blanch, stir-fry with soy sauce and cooking wine, add water to boil, and simmer slowly. You can poke the trotters with chopsticks for about 20 minutes, and then you can get off. Then add sugar and salt and simmer until the trotters are cooked. If you add soybeans, you'd better soak them for half a day in advance. Pig's trotters are cooked, and soybeans should be cooked before eating. Finally, put some monosodium glutamate and chopped green onion to eat.
