How long does it take to cook rock crabs?

In a large covered stockpot, bring the beer, sugar, seafood seasoning, vinegar, and spices to a boil over medium-high heat. Add the crabs and stir well. Cover and steam 5-7 minutes (10-15 for raw crabs), stirring well a few times. Remove crabs and serve hot, sprinkled with a little extra seafood seasoning, if desired.
