I've never cooked a crab before -- someone else does it or I just buy it cooked at the store. Since the season just began I decided to buy one and try cooking it myself. However, all the recipes I've found so far refer to live crab or frozen crab, neither of which I have. I just bought it fresh from the tank but had the guy cut it up. I was thinking about just having it plain with garlic butter, but how should I cook it? Steam it? Boil it? And for how long? Prior to it being chopped up, it was 2.75 lbs. It's less now because it doesn't have the big shell. And when it's cooked, how can I tell it's done?
