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

What each ingredient does

Oysters
Serve as the main raw base, giving the cocktail its briny, delicate flesh.
Lemon juice
Adds acidity that brightens the oyster flavour and cuts its richness.
Horseradish
Adds sharp pungency that gives the cocktail a pleasant heat.
Tomato ketchup
Adds sweetness and body to the tangy, spiced sauce.

The step that matters

Serve very cold. Oysters are best kept chilled from shucking to serving, since low temperatures slow spoilage and keep the flesh firm and fresh-tasting. Serving them cold also keeps the sauce crisp in flavour.

Swap the lemon

How well each one fits the dish's main ingredients (oyster, sauce, horseradish, tomato, ketchup):
