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.
