Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heavy cream
- Whipped to stiff peaks, it gives the sauce its light, airy body.
- Grated horseradish
- Supplies the sharp, pungent heat that defines the sauce.
- Vinegar
- Adds acidity that brightens the sauce and cuts the richness of the cream.
- Mustard
- Adds sharpness and aroma that complements the horseradish.
The step that matters
Fold gently into the whipped cream. Whipped cream is a foam held up by trapped air. Vigorous stirring deflates it, so the sauce turns dense and loose. Folding in gradually keeps the air and the light texture.
