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 ↓
Ripe Cucumber Pickles
Ingredients
Directions
Prepare the cucumbers
Peel the cucumbers and halve them.
Scrape out the inside and soft part with a silver spoon.
Sprinkle coarse sea salt over the cucumbers and let them sit for 12 hours.
Wipe the cucumbers dry with a towel and cut them into pieces or strips.
Pack the jar
In a jar, layer mustard seeds, cloves, and black pepper, followed by a layer of cucumbers.
Add a piece of horseradish if desired.
Boil enough vinegar to cover the cucumbers and let it cool.
Pour the cooled vinegar over the cucumbers.
After one week, boil more vinegar and pour it over the cucumbers again.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main body of the pickle and stay crisp when salted and kept in vinegar.
- Coarse sea salt
- Draws water out of the cucumbers, firming their texture before pickling.
- Vinegar
- Acidity that preserves the cucumbers and gives them their sharp, tangy flavour.
- Mustard seeds
- Add a pungent, slightly bitter aroma that infuses into the vinegar and cucumbers.
The step that matters
Wipe the cucumbers dry before packing. Salting draws out water, and leftover surface moisture would dilute the vinegar and weaken its preserving acidity, so the cucumbers must be patted dry before going into the jar.
Swap the horseradish
The recipe marks horseradish as optional. How well each one fits the dish's main ingredients (cucumber, mustard, clove, pepper, vinegar):
- Horseradishthe original
- Lettucefits about as well
- Radishfits about as well
- Shallotfits less well
Fit is the average pairing score against cucumber, mustard, clove, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
