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.
Crabs are cooked by boiling in salted water. Crabs are generally either placed live into the boiling pot or killed just prior to cooking. Do not use crabs that have been dead for more than a couple of hours without being cooked. Use 1/4 cup salt per quart of water. Bring the water to a boil. Introduce the crabs and return to a boil. Boil for about 20 minutes.
