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
- Cucumbers
- Main vegetable that is cured and pickled, becoming firm and crisp through brining.
- Coarse salt
- Draws water out of the cucumbers and seasons them during the long brine soak.
- Vinegar
- Provides the acidity that preserves the pickles and gives them their sharp flavor.
- Mixed spices
- Infuse the vinegar with aroma, adding warm and savory flavor to the pickles.
The step that matters
Return the vinegar to the pickles after reheating. The vinegar must be hot and fully covering the cucumbers so the acid and spice flavors penetrate evenly and the pickles stay submerged and preserved.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, clove, horseradish, pepper, celery, mustard, allspice):
- Lettucefits better
- Turnipfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against cucumber, clove, horseradish, pepper, celery, mustard, allspice. Candidates are from the same food group and used in at least 100 recipes.
