how long to cook a live crab
Only cook live crabs, because they deteriorate very quickly after they have expired. You can simply throw the crabs in a pot of boiling water to cook them. Depending on the size of the crabs, it will take between 6 and 10 minutes for them to cook thoroughly. If the crab is alive when you start, the amount of cooking time has very little to do with safety  it s more a question of whether the meat is underdone, overdone, or cooked just right.
