The reason why mung beans are not ripe for a long time is that they are too hard. You should soak in water for about half an hour in advance, and then cook until it blooms. Another way is to fry in a pot for about ten minutes without frying. If you continue to cook after frying, it will bloom very easily, but you can't fry it. In addition, if you put water and mung beans in a pressure cooker for about half an hour, they will cook quickly and badly. To cook mung beans, we can put all the mung beans in when the water is cold, stir them with a spoon, then cook for a few minutes on high fire, turn off the fire, stew for about half an hour before firing, then cook for another 20 minutes, and all the mung beans will bloom after opening. The mung bean soup made in this way is rich in nutrition and rich in taste, but it takes a little more time. But it's easier than cooking for half an hour. You can also put mung beans in a bowl, put some water in the freezer of the refrigerator for about half an hour, freeze them with ice cubes, and then take them out and cook them in boiling water. When they are cold and hot, they will swell and shrink, and the nutrients will come out, which will save time and ensure nutrition. Soak the beans for about three hours in advance, wash them, and cook them in the fire for about ten minutes before they bloom. This method is also the simplest and quickest, and it tastes very delicious, suitable for people who are in a hurry, but you can't eat hot tofu in a hurry. If you want to make it more delicious, you must cook it for a long time. If you want to drink thick soup, put less water. When cooking beans, you can't cook beans that have been left for a long time, which will taste bad. Boiled beans can be made in casserole, which is beautiful and delicious.

Moreover, mung beans will grow into mung beans in water and can be cooked and eaten. No matter what food it goes with, it is a very delicious dish.
