Cocktail Sauce
 

2 cups ketchup
1 pat butter
1 TB sugar
2 TB horseradish
1 ts lemon juice

Mix all ingredients together in a small cooking pot. I usually start the cocktail sauce before I start cooking my shrimp. I put it on high then once it starts to bubble I move the pot to another burner and heat on low while cooking the shrimp, stirring the cocktail sauce occasionally.
