According to the data of Kyushu Drunk Catering Network, the best time is to steam frozen Portunus for 8- 10 minutes. It is suggested that the frozen Portunus trituberculatus should be thawed first and then steamed in the pot, because the thawed Portunus trituberculatus will have a small amount of juice flowing back, and the taste and taste will be better. If it is a cooked and frozen swimming crab, it can be steamed directly in the pot without thawing, but be careful not to steam for more than ten minutes, so as to avoid the evaporation of water in the crab meat, which will make the crab meat become firewood and affect the taste.
