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 a firm, chunky texture.
- Cabbage
- Adds crunch and body to the mixture as it pickles.
- Mustard seed
- Contributes a sharp, pungent aroma and flavour to the pickle.
- Cider vinegar
- Provides acidity that preserves the vegetables and gives the pickle its tang.
- Cucumbers
- Add crisp texture and fresh flavour to the chopped mixture.
- Horseradish
- Adds a sharp, pungent heat that intensifies with time in the pickle.
The step that matters
Drain and dry the mixture. Salt water draws moisture out of the vegetables; if they stay wet before the vinegar is added, the pickle will be watery and dilute the vinegar's preserving strength.
