Put the shrimp, garlic, parsley, Old Bay and beer into a pot, give it all a stir and bring it to a boil over high heat.
Let the shrimp simmer until they are opaque (about 2 minutes) and then scoop them out onto a platter or bowls to cool off a little.
While the shrimp are cooling, make the dipping sauce by stirring together the melted butter, lemon juice and Worcestershire sauce. Divide the sauce into individual containers (I like to use tiny prep bowls for this).
Serve up the shrimp in the shell, letting people peel their own. Put a bowl in the middle of the table so folks have a place to toss the shells, and instead of napkins, hand out individual wet washcloths for their hands.
Notes
Shrimp: We recommend getting your shrimp from the seafood counter at your grocery store (rather than frozen ones) ideally on the day you are making this dish, or at the most one day before. We like large or extra large shrimp!
Old Bay: Look for this seafood seasoning mix in in the spice aisle of your supermarket
Beer: We tend to use a lighter beer for this recipe, but you can use whatever kind of beer you like. The shrimp will take on a little of the taste of whatever beer you choose.
