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

What each ingredient does

Beef pot-liquor
Provides the liquid base and savoury beef flavour of the sauce.
Butter
Adds richness and smooth body to the sauce.
Flour
Thickens the liquid as it cooks with the butter.
Egg white
Whipped in off the heat to lighten the sauce and add a silkier texture.
Grated horseradish
Supplies the sharp, pungent heat that defines the sauce.
Lemon juice
Adds acidity that brightens the sharpness of the horseradish.

The step that matters

Remove from heat and whip in the whisked egg white. The egg white proteins begin to set and can scramble or curdle in a hot liquid. Taking the sauce off the heat first lets the white blend in smoothly and keeps the sauce light and even.
