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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main body of the pickles and take on flavour from the brine.
- Cold vinegar
- Provides the acidity that preserves and sharpens the pickles.
- Coarse sea salt
- Draws water out of the cucumbers and seasons the pickles.
- Alum
- Helps the cucumbers stay firm and crisp during pickling.
The step that matters
Fill the jars with cold vinegar and screw the lids on tightly. The vinegar must fully cover the cucumbers and the jars must seal well, because acidity and an airtight seal are what keep the pickles safe and stop spoilage from spreading.
Swap the cucumber
How well each one fits the dish's main ingredients (pepper, horseradish, mustard, vinegar):
- Radishfits better
- Shallotfits better
- Broccolifits better
- Cucumberthe original
Fit is the average pairing score against pepper, horseradish, mustard, vinegar. Candidates are from the same food group and used in at least 100 recipes.
