Tips for stir-frying green beans:
1. It means oiling first, and after a few minutes, when the surface of the beans begins to wrinkle after dehydration, immediately remove and control the oil. Dehydrate the surface of the beans, thus retaining the light green color of the beans themselves.
2. When frying green beans for the second time, the heat must not be too big, otherwise it is difficult to control the oil temperature and it is very easy to fry the beans.
