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 ↓

Directions
Prepare the cucumbers
Pour boiling hot water over the cucumbers and let them stand for 24 hours.
Wipe the cucumbers dry and pack them into jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider vinegar
- Provides the acidity that preserves the pickles and gives them their sharp flavor.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Salt
- Seasons the brine and helps draw flavor into the cucumbers.
- Alum
- Helps the cucumbers stay firm and crisp during pickling.
- Whole mustard seed
- Adds a pungent, earthy flavor to the brine.
The step that matters
Pour the boiling brine over the pickles. The brine must be fully boiling when poured so it penetrates the cucumbers and begins preserving them. A lukewarm brine can leave the pickles less safe and more prone to spoilage.
Swap the clove
How well each one fits the dish's main ingredients (cucumber, cider, vinegar, allspice, mustard, sugar, horseradish):
- Tarragonfits better
- Cinnamonfits about as well
- Capersfits about as well
- Clovethe original
Fit is the average pairing score against cucumber, cider, vinegar, allspice, mustard, sugar, horseradish. Candidates are from the same food group and used in at least 100 recipes.
