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 body, softening the bite of the horseradish.
- Mustard
- Adds sharpness and extra pungency to the sauce.
- Vinegar
- Adds acidity that brightens the flavor and sharpens the heat.
- Saccharine
- Adds sweetness to balance the sharpness of the vinegar and horseradish.
The step that matters
Serve immediately.. Horseradish releases its pungent compounds when grated and cut, and these volatile compounds fade over time and with heat. Serving right away keeps the sauce sharp and hot.
