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 body and briny flavor of the cocktail.
Prepared horseradish
Adds sharp heat that cuts through the richness of the oysters.
Tomato ketchup
Gives the dressing sweetness, body, and a tangy tomato base.
Vinegar
Adds acidity that brightens the dressing and balances the sweetness.
Lemon juice
Contributes further acidity and fresh citrus aroma to the dressing.

The step that matters

Chill the oysters thoroughly. Cold oysters stay firm and fresh-tasting, while warm ones soften and spoil quickly. Keeping everything cold also keeps the dressing crisp and the sharp flavors balanced.

Swap the lemon
