Steaming the frozen Portunus trituberculatus after thawing can not only shorten the cooking time, but also make the crab meat evenly heated and completely steamed. If it is not thawed and steamed directly, it may lead to different internal and external maturity of crab meat and affect the taste.

Thawed Portunus can be thawed naturally at room temperature, or it can be thawed by adding salt in cold water. The former takes a long time, while the latter takes a short time, which can reduce the growth of bacteria.

The frozen swimming crab can smell if there is any odor during thawing. If there is odor, it may be frozen after death, and the inside has gone bad. It is best not to continue eating.

How long does it take to steam Portunus?

No matter whether the swimming crab is steamed in cold water or boiling water, after the steamer is boiled, the swimming crab with less than 3 pairs should continue steaming for about 10 minute, the swimming crab with 3-4 pairs should continue steaming for about 12 minute, and the swimming crab with more than 4 pairs should continue steaming for about 15 minute. Usually, for every weight gain of 1 2, the steaming time increases by about 2 minutes.
