Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Horseradish (in the method): Provides the sharp, pungent heat that defines the sauce.
Cream: Adds richness and body, mellowing the sharpness of the horseradish.
Breadcrumbs: Soaked in milk, they thicken the sauce and add body.
Powdered sugar: Adds a little sweetness to balance the heat and acidity.
Vinegar: Adds acidity that brightens the flavour and sharpens the heat.
