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.
- Horseradish
- Adds sharp pungency that cuts through the richness of the oysters.
- Tomato ketchup
- Adds sweetness and body to the sauce.
- White wine vinegar
- Adds acidity that brightens the sauce and balances the sweetness.
- Lemon juice
- Adds acidity and fresh aroma that complements the oysters.
The step that matters
Chill for at least 20 minutes. Cold keeps the oysters firm and fresh-tasting, and lets the sauce chill and absorb flavour before serving. Serving warm would soften the oysters and dull the sharp, bright seasoning.
Swap the white pepper
How well each one fits the dish's main ingredients (horseradish, tomato, ketchup, white wine, vinegar, lemon, oyster):
- Tarragonfits better
- Capersfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against horseradish, tomato, ketchup, white wine, vinegar, lemon, oyster. Candidates are from the same food group and used in at least 100 recipes.
