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 ↓
Cucumber Pickles
Ingredients
Directions
Layer and spice
Slice the peppers, onions, and horseradish. Place them in jars with the cucumbers.
Combine the spices and sugar in the vinegar, scald it, and pour it over the cucumbers.
Brine overnight
Make a brine that will float an egg and leave the cucumbers in it overnight.
Scald and pack
Drain the cucumbers and scald them in a mixture of 1 quart vinegar and 1 quart water with alum the size of a hickory nut dissolved in it.
Drain again and pack the cucumbers into jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- The main vegetable, which softens in brine and takes on the pickling flavors.
- Vinegar
- Adds acidity that preserves the pickles and gives them their sharp, tangy taste.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar.
- White mustard seed
- Contributes a mild, pungent flavor that defines the pickling spice blend.
- Alum (in the method)
- Helps firm the cucumber tissue so the pickles stay crisper.
- Cinnamon stick
- Adds warm aroma and sweet spice notes to the pickling liquid.
