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 ↓
Pickled Cucumbers
Ingredients
Directions
Make the brine
Dissolve 1 pint of coarse salt in 6 quarts of boiling water to make a brine, then boil and skim it clear.
Wash 150 small cucumbers and soak them in the brine for 48 hours, covered.
Drain the cucumbers and soak them in cold water for 2 hours, then drain again.
Pack and pickle
Place the cucumbers in a crock with the onion, horseradish, red peppers, and alum.
Boil the mixed spices in enough vinegar to cover the cucumbers for 10 minutes.
Put the spice bag in the crock with the cucumbers and pour off the vinegar after 3 days.
Reheat the vinegar and return it to the pickles.
Let sit for 3 weeks before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- The main vegetable that is firmed and flavored by the brine and vinegar.
- Coarse salt
- Draws water out of the cucumbers and seasons them during the brine soak.
- Vinegar
- Provides the acidity that preserves the pickles and gives them their sour flavor.
- Alum
- Helps keep the cucumbers firm and crisp during pickling.
- Horseradish root
- Adds a sharp, pungent flavor that infuses the pickles.
The step that matters
Soak in the brine for 48 hours. Salt draws water out of the cucumbers and firms their flesh; soaking too briefly leaves them soft, while the timed soak controls how much salt penetrates.
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.
