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 ↓
To Pickle Green or Red Capsicums

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Capsicums
- The main vegetable, which softens and takes on the flavour of the pickling liquid.
- Vinegar
- Its acidity preserves the peppers and gives them a sharp, tangy taste.
The step that matters
Pouring the hot brine over the peppers. Hot liquid helps the salt dissolve fully and begins softening the peppers so the brine can penetrate evenly. Letting it cool completely before covering keeps the jar from trapping heat and moisture.
Swap the capsicum
How well each one fits the dish's main ingredients (vinegar, mustard, shallot, horseradish, white wine):
- Chivefits better
- Beetrootfits better
- Radishfits better
- Capsicumthe original
Fit is the average pairing score against vinegar, mustard, shallot, horseradish, white wine. Candidates are from the same food group and used in at least 100 recipes.
