Preheat oven to 400 degrees F. Place a wire rack in a large shallow baking pan. Remove the shrimp from the marinade and place each one in a single layer on the rack, not touching. Add the melted butter to the reserved marinade and mix together well. With a spoon, dribble a little over each shrimp until all of it is used. Bake in the preheated oven for 20 minutes or until the shrimp is opaque. Serve immediately. 235 calories/serving; GL=0, Glycals=0
