The cooking time of crabs is generally about 20 to 30 minutes, and the standard of steaming is that crab shells turn red completely.

1. Tie the crab legs tightly before steaming to prevent them from falling off.

2. When cooking crabs, you can put seasonings such as chopped green onion, coriander, cooking wine and garlic.

Don't open the cooking process, cook it thoroughly at one time, otherwise it will affect the taste of the crab.

4. In the process of steaming, you can chop or dice ginger and put it in vinegar, then dip it in vinegar after steaming.
