First, peel off the beans from the fresh edamame, pour a proper amount of water into the pot, add a spoonful of salt after boiling, pour in the edamame, blanch for about 1 min until the edamame turns green, take it out quickly and cool it quickly, so that the edamame can be kept green.
After the edamame is completely cooled, take it out, drain it, spread it out and dry it until there is no water on the surface of edamame, put it in fresh-keeping bags, each bag is enough for one meal, tie the bag tightly, and then put it in the freezer for freezing preservation. Just take it out and thaw it when you eat it.
Similarly, first peel the beans in the fresh edamame, wash and drain (or not drain), pour an appropriate amount of oil into the pot when cooking, add edamame after the oil is hot, stir-fry until the edamame changes color, and then take it out and air it completely. Then put it into a fresh-keeping bag and put it in the refrigerator for frozen storage. Take out a bag to thaw when eating.
The preserved edamame has no beany smell and is fresh and tender. It's not bad to keep it for a year, and the method is simple.
