Fresh crabs can be frozen directly in the freezer of the refrigerator, but it feels too rude. Moreover, crab is an aquatic product. When we eat them, the most important thing is to eat the delicious taste of seafood. If we cook them in the freezer, the taste will be greatly reduced, and the meat will burn, and the crabs that may be more easily recognized will have a heavier taste. So it will lose the flavor of seafood. It's better not to do this. It is suggested to keep live crabs for a short time and store them in cold storage.
