2. Practice: Wash the mung beans first. Soak the washed mung beans in boiling water for about half an hour. Pour the right amount of water into the pot and turn on the fire. Add the soaked mung beans and cook for 10 minutes. If you want to get rid of fire, be careful not to cook mung bean soup for too long. The soup cooked in this way is green and clear, which is most suitable for reducing internal heat. Because the heat-clearing function of mung beans lies in their skins, don't boil all the skins of mung beans. In addition, if you drink mung bean soup to reduce fire and relieve summer heat, you don't need to eat beans together when drinking. Just pour out the soup and drink it. The remaining mung beans can also be used to continue cooking mung bean porridge.
