I think cooking Dungeness crab is one of the easiest thing in life. Best month of the year to buy cheap Dungeness is November and December. I saw the cheapest was $3.99 per pound, and each crab ranges from 2 to 3 pounds. The cooking process is buy, kill, cut, cook, and eat.
Cut your crab into pieces
Have your wok already
Put your pieces into the wok
Put the lid on
Open the lid and you should see the crab juice is flowing at the bottom of the wok
Wait 1 or 2 more mins, then plate it
Optionally, you can use the juice to cook mushrooms and noodle.
