What each ingredient does

Whipped cream: Adds richness and a smooth, creamy body that softens the horseradish bite.
Grated horse-radish: Provides the sharp, pungent heat that defines the sauce.
White vinegar: Adds acidity that brightens the flavor and cuts through the cream.
Mixed mustard: Contributes sharpness and depth that complements the horseradish heat.
