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
- Green tomatoes
- Form the bulk of the pickle and give it its tart, firm body.
- Cabbage
- Adds crunch and bulk, holding texture through the pickling.
- Onions
- Contribute savory flavor and aroma to the pickle.
- Mustard seed
- Adds pungent, sharp flavor that mellows as the pickle sits.
- Cold vinegar
- Provides acidity that preserves the vegetables and sharpens the flavor.
- Horseradish
- Contributes a sharp, pungent heat and aroma.
The step that matters
Draining and rinsing after the salt soak. Salting draws water out of the vegetables, and rinsing removes excess salt. Thorough draining keeps the pickle crisp and stops surplus liquid from diluting the vinegar, while leftover salt would make it too harsh.
Swap the tomato
How well each one fits the dish's main ingredients (cabbage, onion, horseradish, mustard, pepper, clove, vinegar):
