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 of the cocktail, served cold so they stay firm and fresh-tasting.
- Lemon juice
- Adds acidity that brightens the dressing and balances the briny oyster flavour.
- Tomato ketchup
- Adds sweetness and body to the dressing, softening the sharp seasonings.
- Grated horseradish
- Contributes a sharp, pungent heat that cuts through the richness of the oysters.
The step that matters
Pour the dressing over the oysters just before serving. Acid in the lemon juice and dressing gradually firms and whitens the oyster flesh, so dressing too early makes the oysters tough and less fresh-tasting.
Swap the lemon
