This is a tried and true recipe that we used in
a restaurant where I worked. I get requests every
time I make it.

Easy Shrimp Cocktail Sauce

1 cup Heinz Ketchup
1 tsp Lemon juice
1 tsp Worchestershire Sauce
3 Tbsp horseradish (most grocery stores carry
Kraft cream style prepared horseradish in the
dairy case)
Texas Pete to taste (2-3 squirts is usually enough)

Mix these ingredients in a bowl and let stand for
about 10 minutes for the flavor to develop.

You can easily adjust the horseradish and hot sauce
amounts to suit your own taste.
