Why it works: Mustard and horseradish 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
- Cider vinegar
- Provides the acidic liquid base that carries and extracts the spice flavors.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Horseradish
- Contributes a pungent, sharp heat that infuses into the vinegar over time.
- Mustard seed
- Adds a sharp, pungent flavor that mellows as it steeps in the vinegar.
The step that matters
Let it sit for at least 2 weeks. Flavors are drawn out of the spices and horseradish slowly by the acidic liquid, so a short steep yields a weak, harsh vinegar. Shaking helps distribute the dissolved sugar and extracted flavors evenly.
Swap the celery
How well each one fits the dish's main ingredients (cider, vinegar, sugar, allspice, mustard, cinnamon, horseradish):
- Clovefits better
- Nutmegfits better
- Tarragonfits better
- Celerythe original
Fit is the average pairing score against cider, vinegar, sugar, allspice, mustard, cinnamon, horseradish. Candidates are from the same food group and used in at least 100 recipes.
