Blue crabs? Heathen!
[shakes head]
If they have been cooked with sufficient quantity of McCormick's Old Bay seasoning, as God intended, there will be enough cayenne present to make your lips burn as you scarf the meat fresh out of the shell. You need cold beer with them to dampen down the fire.
Blue crabs are one of the few subjects in which I own up to my Maryland heritage.
Shellfish are just an excuse eat sauce.
