PM Update: Scattered showers and thunderstorms through the early evening. Much cooler on Monday. You may have to dodge some raindrops through about 8 tonight. A cold front moves through tomorrow morning and ushers in much more seasonable weather.
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.
Crab legs will take from 5 to 7 minutes to steam or boil, 7 to 10 minutes to bake (if you include 1/8 inch of water in the baking pan) or 2 to 4 minutes to microwave. Dry methods of preparation, such as baking without water or grilling, may take up to 16 minutes.now crabs and King crabs have large meaty legs that are removed from the crab on the boat, cooked, and flash frozen to enable them to be transported and stored without degrading in quality. So, if you see crab legs in the fish market, they are probably already cooked.
