Boiling is the most common way to cook crabs and a favorite for all varieties. 1  Bring a large pot of water to a boil. Make sure to salt it enough so it tastes as salty as ocean water. 2  Add the crabs as quickly after one another as possible, so they cook for the same amount of time.
Bring an inch of salted water to a boil in a large pot. Put the crabs in a steamer basket or insert, or simply pile them into the pot and let the bottom crabs boil slightly and act as a platform for the other crabs to steam. Cover and cook 10 to 20 minutes, depending on the size of the crabs.
