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

What each ingredient does

Egg yolks
Enrich the sauce and help it thicken as it cooks, giving a rich texture.
Sugar
Adds sweetness and balances the sharpness of the lemon.
Lemon juice
Adds acidity and bright lemon flavour.
Butter
Adds fat for a smooth, rich mouthfeel.
Corn starch
Thickens the sauce as it heats, giving it body.

The step that matters

Stir the mixture into the boiling water until it thickens. Egg yolks can curdle or scramble if they get too hot too quickly. Stirring the mixture into the boiling water while mixing constantly helps distribute the heat evenly and keeps the sauce smooth as it thickens.
