Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Horseradish
- Provides the main sharp, pungent heat of the sauce.
- Vinegar
- Adds acidity that brightens the sauce and sharpens its flavour.
- Thick cream
- Adds moisture and richness, softening the bite of the horseradish.
- Castor sugar
- Adds a little sweetness that balances the heat and acidity.
- Mixed mustard
- Adds further sharpness and a tangy, mustardy note.
The step that matters
Grate the horseradish and mix it in promptly. Grating ruptures the root's cells and releases volatile compounds that give horseradish its heat. These fade with air and time, so mixing soon after grating, with the vinegar, helps keep the sauce sharp.
