Rinse and drain shrimp and place them, unpeeled, in a single layer in a large shallow baking pan. Cut each stick of butter in two to make eight pieces and place on top of the shrimp. Grind peppercorns in a spice grinder or blender to make 1/2 cup and sprinkle the pepper evenly over the shrimp. Bake at 350°s; F for 45 minutes, turning the shrimp at least twice to absorb the pepper-butter on all sides.
Serve directly from the pan with a loaf of sliced French bread so that guests can peel the shrimp as they go and sop up the sauce with hunks of bread.Makes 4 to 8 Source:
