Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Horseradish
- Provides the sharp, pungent heat that defines the sauce.
- Cream
- Adds richness and a smooth texture that mellows the horseradish bite.
- Mustard
- Adds extra sharpness and a savoury depth that complements the horseradish.
- Vinegar
- Adds acidity that brightens the flavour and helps stabilise the sharp pungency.
The step that matters
Add vinegar and mix thoroughly. Grating horseradish releases pungent compounds through enzyme activity, and acid slows this reaction, which helps set the heat level. Thorough mixing spreads the vinegar evenly so the sauce tastes consistent throughout.
