Wash pig's feet, be sure to wash them very clean.
Put the pig's feet in the casserole, add cold water and stew them together, because only in this way can the pig's feet have enough time to stew. After about 2 hours, add the soaked soybeans, add three pieces of ginger, and simmer for one hour.
Attention should be paid to the details: the cooking time should not overflow the soup, and the lid should not be lifted in the middle for inspection. When the stew is ready to eat, season it with salt. If it is not especially for umami flavor, it is best not to add monosodium glutamate or chicken essence. This pot of soup itself is fresh enough, which is a unique fresh stew of soybeans and pig's trotters. This soup is allowed to be a little salty.
Make p.s.
Soybeans must be cooked, because raw soybeans or raw soybeans contain antitrypsin and thrombin, which is extremely harmful to the human body. When digested, it will produce too much gas, causing bloating and indigestion.
Don't worry, it won't!
