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

What each ingredient does

Butter
Adds fat and richness, giving the sauce a smooth, rounded mouthfeel.
Sugar
Provides sweetness and, creamed with butter, helps build a light base.
Egg
Thickens as it heats and sets the sauce to a creamy texture.
Lemon
Contributes acidity and bright lemon aroma that balances the sweetness.

The step that matters

Cooking over boiling water without curdling. Egg proteins thicken when heated, but too much heat makes them tighten and separate. Gentle, steady heat over boiling water lets the sauce become creamy instead of grainy or curdled.
