Why it works: Horseradish and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,646 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
- Horseradish
- Supplies the sharp, pungent flavour that the vinegar draws out over the steeping time.
- Strong vinegar
- Acts as the solvent that extracts flavour from the horseradish and peppers and gives the sour bite.
- Black pepper
- Adds a warm, sharp aroma and background heat to the infused vinegar.
- Cayenne pepper
- Contributes direct chilli heat that builds in the vinegar as it steeps.
The step that matters
Pour the vinegar boiling hot over the dry ingredients. Heat helps the vinegar penetrate the plant material and pull out its volatile flavour compounds faster. Sealing the container while it steeps keeps those aromatic compounds from escaping, so the infusion stays strong.
Swap the horseradish
How well each one fits the dish's main ingredients (vinegar, pepper):
