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 ↓

Directions
Prepare the vegetables
Layer sliced green tomatoes and onions in a jar, sprinkling each layer with salt.
Let the mixture stand overnight.
Drain the vegetables and add vinegar, brown sugar, cloves, and the muslin bag with cinnamon.

Once cooled, add grated horseradish and mustard seed.
Cover with a plate and a weight, and store in a cool cellar.

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 soften into tender pieces during cooking.
- Onions
- Add sweetness and savory flavor that balances the vinegar.
- Vinegar
- Provides acidity that preserves the pickle and gives it its sharp taste.
- Brown sugar
- Adds sweetness and depth that offsets the acidity of the vinegar.
- Coarse sea salt
- Draws moisture out of the vegetables, firming them before cooking.
- Horseradish
- Contributes a sharp, pungent heat that develops after cooling.
The step that matters
Drain the vegetables after salting. Salting draws out a lot of water; draining well before adding vinegar keeps the liquid from diluting the brine and keeps the pickle firm rather than soggy.
Swap the tomato
How well each one fits the dish's main ingredients (onion, vinegar, sugar, clove, cinnamon, horseradish, mustard):
