Name: Oyster Cocktail
Ingredients: 1 pint small oysters; 3 tablespoons Rhine wine; 12 tablespoons catsup; Cayenne pepper to taste; Coarse sea salt to taste; 3 tablespoons tarragon vinegar; Juice of 1 lemon; ¼ teaspoon grated horseradish

Why it works: Tarragon and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,137 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

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 flavor of the cocktail.
Catsup: Adds sweetness and body to the sauce.
Tarragon vinegar: Adds acidity that sharpens the sauce and balances the sweetness of the catsup.
Lemon juice: Adds acidity and brightness to the sauce.
Rhine wine: Adds acidity and mild fruity aroma to the sauce.
Grated horseradish: Adds pungent heat and aroma on top of each portion.

The step that matters

Serve very cold. Cold keeps the oysters firm and fresh-tasting and slows bacterial growth, so they should be chilled right up to serving.

Swap the horseradish
