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

What each ingredient does

Egg yolk
Adds richness and body to the sauce.
Egg white
Adds air when beaten, lightening the sauce's texture.
Sugar
Sweetens the sauce and dissolves into the yolk.
Milk
Forms the liquid base of the sauce.
Vanilla extract
Adds aroma and flavour.

The step that matters

Fold in the beaten egg white. Egg white foam holds air that gives the sauce its lightness. Stirring vigorously or overmixing deflates the foam and makes the sauce heavier.
