2 cups beer
1 tablespoon chopped chives
1 tablespoon fresh chopped parsley
2 teaspoons dry mustard
1/8 teaspoon garlic powder
1 teaspoon salt
1/2 teaspoon freshly-ground black pepper
2 pounds raw medium shrimp

Shell shrimp, except for tails. Blend beer with all ingredients except shrimp. In large bowl with cover, marinate shrimp in this mixture. Refrigerate overnight. Stir occasionally so that all shrimp are evenly seasoned. Drain shrimp. Boil 3 inches from heat source for about 2 minutes on each side.

Serve immediately.
