Boil the vinegar and pour it over the mixture.
Cover the vessel and let it stand in a warm place for about 10 days.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated horseradish
- Provides the sharp, pungent heat that flavours the vinegar.
- Malt vinegar
- Acts as the liquid that extracts horseradish flavour and provides sharpness.
- Cayenne pepper
- Adds additional heat and pungency to the infused vinegar.
- Shallots
- Contribute a mild savoury, aromatic background flavour.
The step that matters
Letting the mixture stand for about 10 days. Steeping gives the vinegar time to extract flavour from the horseradish and shallots; too short a steep yields a weak, thin-tasting condiment.
Swap the horseradish
How well each one fits the dish's main ingredients (shallot, pepper, malt, vinegar):
- Mustardfits better

Fit is the average pairing score against shallot, pepper, malt, vinegar. Candidates are from the same food group and used in at least 100 recipes.
