Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and richness, and gives the sauce a smooth, creamy body.
- Egg yolks
- Lecithin-rich yolks emulsify the butter and set into a thick, smooth sauce when gently heated.
- Lemon juice
- Adds acidity that brightens the rich butter and balances the sauce's flavor.
- Veal stock
- Adds savory liquid that loosens the emulsion and deepens the sauce's flavor.
The step that matters
Cooking over the double boiler. Egg yolks scramble if they get too hot. Beating constantly over gentle heat spreads the heat evenly and lets the yolks thicken smoothly into an emulsified sauce.
