Steam pot, 1/2 quart vinegar, put layer in, dose with Old Bay, Wye River or such seasoning, add layers and season. get boiling-steaming 15-20 min. Put bowel of butter in the top to melt last 5 min.
Remove the shell and clean out crab, then add butter to both sides of the crab body, I use a spoon, add spices you like, lemon pepper, garlic ect.. I usually cook a couple dozen using my outside grill, you can remove the claws and steam as usual, the male crabs have the most meat. Awsome
Never have done blue crab ..... I would take dungenous over anything including king crab or lobster.
I pop the shell , clean out crab of lungs and crap, rinse, and break in two. Boil water in big pot with about 1/3 to 1/2 cup of sugar depending on how many crabs I'm cooking. Throw crabs in and cook for 5 minutes. Pull out and serve with butter heated by candle. Thats it for me ....... I don't want old bay or any other seasonings ........ I like the taste of dungenous as it is without changing it anymore them what the butter does.
Don't see blue crab ever sold around here but will try it if I ever see it.
oh and its 5 minutes cooking them here being ya only get ones precooked being a long way from fresh crab .
