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
Peel the cucumbers and halve them.
Scoop out the inside and soft parts 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 and pickle
Layer mustard seeds, cloves, and black pepper in a jar, then add a layer of cucumbers.
Add a piece of horseradish if desired.
Boil enough vinegar to cover the cucumbers and pour it over them once cooled.
After one 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
- The main vegetable, whose texture firms up after salting and then absorbs the pickling liquid.
- Coarse sea salt
- Draws water out of the cucumbers through osmosis, firming their texture for pickling.
- Vinegar
- Provides acidity that preserves the cucumbers and gives them their sharp pickled flavour.
- Mustard seeds
- Release pungent, aromatic flavour into the vinegar as the pickles steep.
The step that matters
Salting the cucumbers for 12 hours. Salt draws water out of the cucumbers by osmosis, which firms their texture and keeps them from diluting the vinegar. Skipping or shortening this rest leaves the pickles soft and watery.
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.
