Crabs and their fellow crustaceans have a sweet, savory nutty element to their flavor that makes them some of the most prized seafoods. Unfortunately, extracting the tasty meat from its hard casing is sometimes hardly worth the effort. That's not the case with Alaskan king crab, which is harvested for its heavy, meaty legs. Usually purchased frozen, they're easily cracked open and yield large portions of sweet, delicate flesh. Cooking the crabs is a simple matter steaming them for a few minutes.
