Material preparation: 2 trotters, 30g onion, 200g kidney bean (white), 20g ginger, 2 star anise, 3 slices of Chinese prickly ash 1 spoon, 20ml white wine, 2 spoons red pepper, vinegar 1 spoon, soy sauce 1 spoon and so on.

1, ask the store to help chop the trotters into small pieces when buying them.

2. Soak kidney beans in warm water for 3-5 hours. If you use cold water, you'd better soak it one night in advance. If the time is too late, you don't have to soak in advance, but the beans cooked in this way are easier to break and affect the appearance.

3. Add enough cold water to the pot, add pig's trotters, pepper, star anise and fragrant leaves, and then blanch the pig's trotters with high fire.

4. Take it out after drowning. If there is a lot of blood foam on the surface, it can be washed off with hot water.

5. Replace the pot with trotters, add enough water (you can put more, the soup is really the essence of this dish) and add ginger slices, onions, salt and white wine.

6. Use the rice cooker to choose the bean gluten stew mode, or you can stew it in a casserole for about 3 hours until the trotters and kidney beans are soft and rotten.

7. Mix a bowl dipped in water with soy sauce, vinegar, red pepper and chopped green onion. Pig's trotters can be dipped in it, which is sour and greasy and has no flavor.
