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.
- Egg yolks
- Add richness and help bind the grated horseradish into a smooth base.
- Whipped cream
- Adds lightness, a soft creamy texture, and mellows the heat.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness.
The step that matters
Folding in the whipped cream. Whipped cream is full of trapped air. Stirring vigorously or overmixing deflates it and makes the sauce thin and dense. Fold gently with a spatula, just until no streaks remain.
