This is the BEST, my mom did this 45 years...

I have done this for years, but only used Ketchup & horseradish. I just put unmeasured amount of ketchup in a container - however much I think I will need... then add small amounts (usually 1/4 tsp.) at a time of the horseradish. Continue to add the horseradish until you get the taste you want. It taste EXACTLY like the store brought version.

Yes, this is the classic shrimp cocktail sauce that I grew up with in the Philadelphia area. Personally I like more horseradish and maybe a touch more Worcestershire, but it is all a matter of taste, of course. This sauce is great with fresh steamed shrimp. Boun Appetito!
