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
- Cabbage
- Forms the bulk of the chopped pickle and gives it a crisp, sturdy texture.
- Coarse sea salt
- Draws water out of the vegetables, firming them and concentrating their flavour before pickling.
- Sugar
- Balances the sharpness of the vinegar and adds sweetness to the pickle.
- Vinegar
- Acidifies the mixture, preserving the vegetables and giving the pickle its tang.
- Grated horseradish
- Adds a sharp, pungent heat that mellows during cooking.
The step that matters
Drain well in the morning. Salt draws out a lot of liquid overnight. If the vegetables are not drained thoroughly, excess water dilutes the vinegar and sugar, leading to a watery, less flavourful pickle.
