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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young beans
- Form the main body of the pickle and take up the brine and vinegar flavor.
- Coarse sea salt
- Draws water out of the beans and seasons them during the brine soak.
- Vinegar
- Acidity that preserves the beans and gives the pickle its sharp flavor.
- Scraped horseradish
- Adds pungent, sharp heat that stands out in the finished pickle.
The step that matters
Soak the beans in the brine until they change color. Salt draws water out of the beans and firms their texture. Stopping too early leaves them soft and under-seasoned, while the color change shows the brine has done its work.
Swap the beans
How well each one fits the dish's main ingredients (vinegar, cabbage, allspice, clove, mustard, horseradish):

Fit is the average pairing score against vinegar, cabbage, allspice, clove, mustard, horseradish. Candidates are from the same food group and used in at least 100 recipes.
