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 body of the cocktail, carrying the sauce in each glass.
- Prepared horseradish
- Adds sharp heat that cuts through the richness of the oysters.
- Tomato ketchup
- Adds sweetness and body to the dressing.
- Vinegar
- Adds acidity that brightens the dressing and balances the sweetness.
- Lemon juice
- Adds acidity and fresh citrus aroma to the dressing.
The step that matters
Keep the oysters and dressing very cold. Cold slows bacterial growth and keeps the oysters firm and fresh-tasting, while warmth makes the shellfish soft and more prone to off flavours.
Swap the lemon
