Frozen crabs need to be thawed before cooking, but they must be heated thoroughly when eating, because seafood is easily contaminated by microorganisms. There are several ways to thaw quick-frozen crabs:

1, cold water thawing: thaw the frozen crabs to a place with temperature, so that the thawing is faster. For aquatic products and fresh meat quick-frozen foods, they should be moved from the freezing room of the refrigerator to the refrigerating room at one to ten degrees Celsius, and the food should be moved several hours to one day in advance; 2. Thaw with salt water: If it is too late to put it in the refrigerator, the crab can be completely thawed in salt water, because salt water can accelerate the melting of ice and will not breed bacteria; 3, add vinegar to thaw: dip the fork into the crab with vinegar, which can speed up the thawing; 4, microwave thawing: when thawing in the microwave oven, be sure to use the lowest gear, and gradually heat. It needs to be heated for about two minutes at first, and then the heating time is determined according to the degree of thawing of crabs until it is completely thawed.
