Pull off the switch cover plate by removing the two screws with a screwdriver. Turn the switch to the on position. Verify that the power is off to the switch by touching one leg of a circuit tester to the ground wire within the box, and the other to one of the two contact screws on the switch.
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.
Make sure the crabs are all covered in water. Boil them until the shells turn red, for approximately 20 minutes counting time after the water comes back to a full boil. They're done! Now, you can cool the crab down by either laying them out on a clean dry towel, like I have illustrated with dungeness crab. Or, you can cool them down by placing them in cool water in a clean sink. Either way is fine, but cooling them with cold water or even over ice is an excellent way to avoid the crab meat sticking to the legs.
