Steam crabs for 20-30 minutes according to the size of crabs. Generally, crabs with a large size can be completely sterilized by steaming for 20 minutes. If they are larger, increase the steaming time as appropriate.

First, note: crabs contain a lot of parasites and impurities, so they should be cleaned in two steps before steaming:

(1) Soak in salt water for more than 2 hours to let crabs spit out impurities and sewage;

(2) Use a toothbrush to brush the whole body of the crab, and don't forget it inside the navel!

Second, tips: when steaming crabs, remember to put the crab shell down and the crab belly up so that the soup will not be lost. (as shown below)

Third, special precautions; Crabs are cold, so pregnant women had better not eat them, and if they eat them, they should be small! ! !
