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, then remove the inside and soft part with a spoon.
Sprinkle with coarse sea salt and let sit for 12 hours.
Wipe dry with a towel and cut into pieces or strips.
Pack the jar
Layer mustard seeds, cloves, and pepper in a jar, then add a layer of cucumbers.
Add a piece of horseradish if desired.
Pickle
Boil enough vinegar to cover the cucumbers and pour it over them once cooled.
After a week, boil more vinegar and pour it over the cucumbers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, watery body that the brine is absorbed into.
- Coarse sea salt
- Draws water out of the cucumbers, firming them and concentrating their flavour before pickling.
- Vinegar
- Acidity that preserves the cucumbers and gives the pickle its sharp, sour taste.
- Mustard seeds
- Add pungent, aromatic flavour that infuses into the cucumbers over time.
The step that matters
Drawing out water with salt. Salt needs the full 12 hours to pull moisture out of the cucumbers. Skipping or shortening this leaves them softer and more diluted, so the pickles lose crispness.
Swap the clove
How well each one fits the dish's main ingredients (cucumber, mustard, pepper, horseradish, vinegar):
- Tarragonfits better
- Capersfits better
- Dillfits better
- Clovethe original
Fit is the average pairing score against cucumber, mustard, pepper, horseradish, vinegar. Candidates are from the same food group and used in at least 100 recipes.
