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 brightens the flavor and sharpens the heat.
Cream
Adds fat and body, softening the sharpness into a smooth sauce.
Mustard
Adds a sharp, pungent note that complements the horseradish.

The step that matters

Adding the cream last. Horseradish's heat comes from volatile compounds released when it is cut and mixed; cream dilutes and mellows that heat, so adding it last lets you judge the sharpness before softening it.
