Very cool. Every time I've done them we boiled them until they changed color in a big stock pot on a turkey fryer burner. Pulled them out and ripped the lids off, top of the shells, then scraped the lungs and innards out with a finger and snapped the bottom half with the legs on it in half before either eating or freezing. Usually eating smile.

Good buddy of mine used to sell them both live and in cooked clusters and I can honestly say I've had the privilege of eating crabs until I was sick of them. We finally stopped when he got the gout!
