Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Horseradish
- Supplies the sharp, pungent bite that defines the sauce.
- Egg yolk
- Emulsifies and thickens the mixture so it holds together smoothly.
- Whipped cream
- Adds volume and a light, creamy texture.
- Sugar
- Mildly balances the sharpness of the horseradish.
The step that matters
Fold in the whipped cream. Folding gently keeps the air trapped in the whipped cream, so the sauce stays light. Vigorous stirring deflates the cream and leaves the sauce dense and heavy.
