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 defines the sauce.
- Sweet cream
- Adds richness and a creamy body that softens the horseradish bite.
- Vinegar
- Adds acidity that brightens the flavor and sharpens the sauce.
- Mixed mustard
- Adds extra sharpness and a second layer of pungency.
- Sugar
- Balances the sharpness of the vinegar and horseradish with sweetness.
The step that matters
Prepare just before serving. The volatile compounds that give horseradish its pungent bite dissipate over time, so the sauce loses heat and punch if it stands too long after mixing.
