2. The steaming time of crabs with different weights is different. Boil the water until it boils. Put the washed crabs into the steamer and slice the onion and ginger, which can not only remove the fishy smell, but also keep the crabs fresh. Generally, crabs weighing more than half a catty (250g) need to be steamed for about 20 minutes, crabs weighing about six ounces (300g) need to be steamed for 25 minutes to be completely sterilized, and crabs weighing less than half a catty only need to be steamed after the water is boiled 12 minutes.
3. The total steaming time should not be less than 15 minutes since it takes about 15 minutes to completely kill parasites or pathogenic microorganisms, which will not lead to crab meat aging.
