King crab meat, chunked, flaked or shredded, can be served hot or cold. For hot menu items, gentle heating is all that’s required. Add to soups and stews during the last 5 minutes of cooking. Legs are often served in the shell with drawn butter. To steam, throw legs in a covered pot with an inch or so of water, bring to a boil and steam just until heated through, about 5 minutes.
