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

What each ingredient does

Oysters: Provide the main briny, savoury flesh that the cocktail is built around.
Lemon juice: Adds acidity that brightens the oysters and balances the heat and sweetness.
Grated horseradish: Adds sharp, pungent heat that cuts through the richness of the oysters.
Red ketchup: Adds sweetness, tang and body to the sauce spooned over the oysters.
