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

What each ingredient does

Egg yolk
Enriches the sauce and helps it set as it cooks and thickens.
Corn starch
Thickens the liquid into a smooth sauce when heated.
Sweet cream
Adds richness and a smooth, silky texture to the sauce.
Horseradish
Provides the sharp, pungent flavour that defines the sauce.
Cider vinegar
Adds acidity that balances the sharpness of the horseradish.

The step that matters

Finish cooking until thickened. Egg yolk can curdle if it overheats, while the starch needs enough heat to thicken. Cook gently and keep stirring so the sauce thickens smoothly without scrambling.
