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

What each ingredient does

Oysters
Provide the main body and briny flavour of the cocktail.
Lemon juice
Adds acidity that brightens the flavour of the sauce.
Vinegar
Adds sharp acidity that balances the heat and sweetness.
Tomato ketchup
Adds sweetness and body to the sauce.
Horseradish
Adds pungent heat that cuts through the oysters' richness.

The step that matters

Let the oysters stand in the sauce for five minutes, then keep it cold. Acid in the sauce firms and whitens the oyster flesh, so the timing matters. Holding the mixture on ice keeps the oysters fresh and safe, and prevents the sauce from warming and the oysters from spoiling.

Swap the lemon
