And put the casserole tightly, boiled for half an hour, Green Beans will bloom crisp, add sugar to become a delicious green bean soup. "Add sugar when you boil, beans are not bad," he reminded.

The good mung bean soup should be immediately rinsed with cold water, cooled, and cooled until it can be refrigerated. This can guarantee a day or so, otherwise it will be easy to “start”.
