Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oysters: Form the base of the cocktail, providing the main texture and briny flavor.
Lemon juice: Adds acidity that brightens the sauce and balances the savory ingredients.
Vinegar: Adds sharp acidity that sharpens the sauce and cuts the richness of the oysters.
Horseradish: Adds pungent heat that gives the sauce its sharp, aromatic bite.
Tomato ketchup: Adds sweetness and body, rounding out the sharpness of the acids and spices.
