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.
- Vinegar
- Adds acidity that balances the sharpness and brightens the flavor.
- Prepared mustard
- Adds sharp, tangy flavor and helps the sauce hold together.
- Powdered sugar
- Adds a little sweetness to soften the sharpness of the horseradish and vinegar.
The step that matters
Stir briskly for 2-3 minutes. Vigorous stirring of the vinegar mixture helps blend the ingredients evenly and lets the sharp pungency develop. Stirring is what keeps the sauce's flavor consistent throughout.
