Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main seafood flavor and the tender body of the cocktail.
- Oyster juice
- Adds briny, savory liquid that carries the oyster flavor into the sauce.
- Lemon juice
- Adds acidity that brightens the sauce and balances the savory and spicy notes.
- Horseradish
- Adds sharp heat that cuts through the richness of the oysters.
- Tomato ketchup
- Adds sweetness and body to the sauce, giving it a rounded red color.
The step that matters
Chill the glasses and oysters before filling. Cold keeps the oysters firm and fresh-tasting and slows bacterial growth, so the cocktail stays crisp and safe to serve. Cooling the glasses first prevents the sauce from warming the oysters as it is poured.
Swap the lemon
