The recipe of "New Egg Soup" is a little different from usual. The skin of tomatoes must be cleaned, cut as small as possible, and stir-fry for an appropriate amount of time. When beating eggs, add them slowly and stir immediately to prevent them from forming lumps. When seasoning, you only need to season it simply, no other seasonings with strong color or flavor are needed. Thickening with water starch is very important, just a thin layer is enough.
