Why it works: Horseradish and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

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):
- Capersfits better
- Tarragonfits better
- Dillfits better
- 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.
