Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oysters
Are the main ingredient, served raw, so they should be kept ice cold.
Horseradish
Adds sharp heat that cuts through the richness of the oysters.
Vinegar
Adds acidity that brightens the sauce and balances its sweetness.
Tomato ketchup
Adds sweetness and body to the sauce.

The step that matters

Ensure the oysters are ice cold. Oysters served raw spoil quickly at room temperature, and cold keeps them firm and fresh-tasting. Chilling the sauce for an hour lets the flavours blend before serving.

Swap the tomato

How well each one fits the dish's main ingredients (oyster, horseradish, sauce, vinegar, ketchup):

  1. Mustardfits better
  2. Shallotfits better
  3. Cucumberfits better
  4. Tomatothe original

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