Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Form the main body of the cocktail, adding briny, savoury flavour and a soft, tender texture.
- Tomato ketchup
- Provides the sweet, tomato-based body of the sauce that the oysters sit in.
- Lemon juice
- Adds acidity that brightens the sauce and balances the sweetness of the ketchup.
- Vinegar
- Adds sharp acidity that lifts the flavour and keeps the sauce tangy.
The step that matters
Chilling the sauce. Cold slows bacterial growth in raw shellfish and keeps the sauce's acidity crisp. Oysters warm quickly, so the sauce should be well chilled and the cocktail kept cold until it is eaten.
Swap the lemon
How well each one fits the dish's main ingredients (oyster, tomato, ketchup, sauce, vinegar):

- Lemonthe original
Fit is the average pairing score against oyster, tomato, ketchup, sauce, vinegar. Candidates are from the same food group and used in at least 100 recipes.
