Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce and add richness as they set gently with heat.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
- Arrowroot or fine flour
- Thickens the sauce so it becomes smooth and glossy when heated.
- Beef gravy
- Supplies the savoury, meaty base of the sauce.
The step that matters
Carefully bring the mixture to a boil, stirring continuously. Egg yolks can curdle or scramble if overheated or left unstirred. Constant stirring spreads heat evenly, letting the yolks and starch thicken the sauce smoothly.
