This is an easy answer. I am going to teach you how to make this from scratch. Many people like to use V8 and clamato for the cocktail sauce but the real secret over here is to make the most amazing and flavorful shrimp broth! I will also be giving you the option to make an easy shrimp cocktail recipe made with V8 or clamato but believe me, the broth won't take more than 8 minutes to get it done and makes all the difference.
