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

What each ingredient does

Butter
Enriches the sauce and adds richness to the base roux.
Flour
Thickens the milk into a smooth sauce when cooked with the butter.
Sweet milk
Forms the liquid base that thickens into the sauce.
Fresh grated horseradish
Provides the sharp, pungent flavour that defines the sauce.
Egg
Adds richness and body to the sauce once it is thickened.

The step that matters

Once thick, add the horseradish and beaten egg.. Egg proteins can scramble if the sauce is too hot when they go in, so the sauce should be thick but off direct high heat. Heat gently afterward to keep it smooth.

Swap the white pepper
