Let me tell you something. I used to do this when I was at school. You can buy braised pork or roasted bones at the farmer's market and ask the boss for soup. Stew beans with this soup and bone. If you like potatoes, you can add some water. In short, the amount of soup exceeds that of beans. The soup is boiling. Try it and add salt. 15-20 minutes to cook (cover the pot). It varies from person to person. /kloc-after 0/0 minutes, you can check whether the soup is cooked, turn the beans every 3-5 minutes and cook evenly. After cooking, add some monosodium glutamate and you're done. Similarly, you can also stew cabbage, tofu and so on. It's delicious to eat with rice, especially with several roommates. It feels great! !
