Maryland Steamed Crabs

When you steam crabs in Maryland, you need a lot of Old Bay seasoning and a lot of beer.  You actually use some of the beer for the steaming. : ) 

In a large steam pot, fill bottom with water, 1 onion, 2 cans beer and 1 packet Zatarain's Crab Boil spice.  Bring to a boil and reduce heat.  Place 1 dozen Maryland Blue Crabs in steam pot top and liberally cover with white vinegar, then Old Bay seasoning.  Steam 10 - 15 minutes until crabs are done.  Serve with Old Bay, malt vinegar, butter and plenty of cold beer.
