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

What each ingredient does

Oil
Forms the base of the dressing and carries the flavours, giving body and richness.
Vinegar
Adds acidity that brightens the dressing and balances the oil.
Hard-boiled egg yolk
Adds richness and body, helping the dressing thicken and feel creamy.
Mustard
Adds sharpness and helps emulsify the oil and vinegar so they stay blended.

The step that matters

Beat until it thickens. Beating whisks oil into the vinegar and other liquids as tiny droplets, forming an emulsion. Stopping too early leaves the dressing thin and likely to separate.

Swap the clove

How well each one fits the dish's main ingredients (vinegar, horseradish, mustard, pepper, sauce, onion, garlic):

  1. Capersfits better
  2. Tarragonfits better
  3. Dillfits better
  4. Clovethe original

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