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.
Place the crab legs in the pot on a rack over the boiling water. When the water starts to boil again, cover with a lid and cook for about six minutes or when they begin to omit a âcooked odorâ, they should be ready to eat.herefore, you should be careful not to overcook them or else they will taste dry and tough. Three drops of hot sauce in butter can really draw out the wonderful taste of fresh king crab. Below are a few simple instructions on how to cook crab legs.
