However, if you don't finish a meal, you don't have to throw it away, but you must refrigerate it in a timely manner and ensure that it is thoroughly heated and sterilized before eating it. For example: take the crab out of the refrigerator, take the meat, and chop it up.
Bring water to a boil in a saucepan, add chicken stock, thicken thinly with a little thickening powder, sprinkle in the crab meat, then stir in the beaten egg mixture, stirring well to turn off the heat immediately. Add a pinch of salt, sprinkle pepper, chopped scallions or chopped scented leaves, and you have a very tasty crab and egg custard. It can also be used to make crab meat fried rice, crab meat stuffed buns and other fully heated flavorful food.
