Why it works: Cucumber and horseradish match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 640 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the main body of the pickle, which firms and crisps during brining.
- Salt
- Draws water out of the cucumbers and seasons them, firming their texture over the two brining days.
- Cider vinegar
- Adds acidity that preserves the pickles and gives them their sharp, tangy flavour.
- Horseradish roots
- Adds a sharp, pungent aroma and flavour to the pickles.
The step that matters
Draining and re-salting the cucumbers. Each brine must be fully drained before the next salt addition, so the cucumbers are not left in water that dilutes the salt. Consistent salt concentration is what draws out moisture and firms the cucumbers, so the timing and draining matter.
Swap the horseradish

Fit is the average pairing score against cucumber, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
