Take a pound of cooked shrimp, the bigger the better, and take the tails off, then lay on a bed of shredded lettuce. Now that is a shrimp cocktail. Now make the cocktail sauce, about a cup of ketchup, and a tablespoon of horseradish, and tablespoon of worcestershire sauce. Stir and let the flavors meld. Serve with a baked potato with sour cream and butter.
