What each ingredient does

Made mustard: Adds sharp, tangy flavor that complements the heat of the horseradish.
White sugar: Balances the sharpness of the vinegar and horseradish with mild sweetness.
Vinegar: Adds acidity that tempers the horseradish and helps it keep its sharp flavor.
Grated horse-radish: Provides the sharp, pungent heat that defines the sauce.
