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 fat and body, mellowing the sharpness and thickening the sauce.
Vinegar: Adds acidity that brightens the flavor and balances the richness of the cream.
Mustard: Adds sharp flavor and helps emulsify the sauce.
Sugar: Adds a touch of sweetness that balances the heat and acidity.

The step that matters

Grate the horseradish using a clean grater.. Grating ruptures the root's cells, releasing the compounds that produce its pungent heat. Keeping the grater clean matters because residual flavors or moisture can dull or alter the sharpness. Heat and acidity develop as the sauce sits, so tasting before adding all the cream helps control the final consistency and bite.
