Method 1If you don't eat it that night, you can wrap it in plastic wrap and put it in the refrigerator after it cools completely. You can also freeze it if you have the conditions. However, the cooked crabs stored in the refrigerator should not be more than noon of the next day at the latest, and remember to cook them again when you eat them again. It is best to put some grated ginger when eating to help sterilize the crab. Eating crabs in this way ensures that you can enjoy the flavor and safety at the same time. Method 2 If you want to eat boiled crabs, try to steam them through before eating, but cover them and put them in the freezer (non-refrigerated) layer of the refrigerator. This is because boiled crabs are poisonous when exposed to fog, dew, etc. , they must be cooked again the next day in boiling water and heated for half an hour after opening so that the microorganisms in the crabs are not completely killed. Avoid eating crabs without seasoning. Since crabs are cool, they should be served with grated ginger and vinegar to prevent hurting the stomach. But if it goes bad, it's best to throw it away. It's a waste, but health is more important. Method 3 If the cooked crab is stored for a short time, you can cover it with plastic wrap and put it in a cool and ventilated place. Generally it can be kept fresh for 6-8 hours, provided that it is cold and the temperature is low. If the weather is hot, if you want to keep boiled crabs for a short time, put them in the refrigerator. At noon such crabs can be kept until evening, but not overnight. If you want to store cooked crabs for a long time, such as overnight, keep them in the freezer. But direct freezing tends to make cooked crabs lose water and become very dry and unpalatable. You can freeze them together with the soup in which the crabs were cooked to keep the fresh flavor of the crabs.
