Easy Shrimp Cocktail

1 c. ketchup
¼ c. grey poupon type Dijon mustard with horseradish, or just horseradish
1 tsp Worcestershire sauce
1 tsp lemon juice
½ tsp Old Bay seasoning
1/8 tsp cayenne pepper

Buy already cooked shrimp that has been frozen, and let it sit in clean cold water until room temperature.  Pat dry with paper towels, and plate with the cocktail sauce.  Best to keep shrimp over ice.

Or even easier:

ketchup
grey poupon
horseradish

Mix in the amounts you desire and serve with cooked, cold, cleaned shrimp
