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 or tinned swiss milk
- Adds richness and body, softening the horseradish's bite.
- Vinegar
- Adds acidity that sharpens flavour and helps keep the heat stable.
- Sugar
- Balances the sharpness of the vinegar and horseradish with mild sweetness.
- Prepared mustard
- Adds a sharp, tangy note that rounds out the heat.
The step that matters
Combining the vinegar with the grated horseradish. Grated horseradish releases its pungent compounds when its cells are broken, and that heat fades as it sits. Acid such as vinegar helps stabilise the sharp flavour, so combine and serve without long delay.
