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

What each ingredient does

Butter
Adds richness and fat, and creaming it with sugar traps air for a light texture.
Sugar
Adds sweetness and, creamed with butter, helps build a light, airy base.
Boiling water
Forms the liquid base of the sauce and melts and dissolves the sugar and butter.
Egg white
Beaten and folded in, it creates a foam that gives the sauce its light, frothy texture.
Cornstarch
Thickens the sauce as it heats, because its starch swells and sets the liquid.

The step that matters

Fold in the beaten egg white last. Folding gently keeps the air trapped in the beaten egg white. Stirring or beating it in would deflate the foam and leave the sauce dense instead of light.
