1. How long does the whole crab steam?

When cooking steamed crabs and other dishes, the whole live crab is usually steamed in a pot. After the steamer is boiled, put the crabs in, steam on high fire for about 5 minutes, and then continue steaming on low fire for a while. The specific steaming time depends on the size of the crab.

3 For crabs of less than two sizes, it takes about 10 minute; for crabs of three to four sizes, it takes about 12 minute; for crabs of more than four sizes, it takes about 15 minute. Usually, for every weight gain 1, the steaming time will increase by about 2 minutes.

2. How long does the diced crab steam?

To cook a dish like crab with scallion oil, you need to cut the crab into small pieces first and then steam it in a pot. Diced crabs also need boiled water. Steam on high fire for 5 minutes, and then steam on low fire for about 10 minutes.

In a word, the total cooking time of the whole crab or diced crab should not be less than 15 minutes from the beginning of boiling water, because it takes about 15 minutes to completely kill parasites or pathogenic microorganisms, which will not lead to crab meat aging.
