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

What each ingredient does

Egg yolks
Add richness and body, and thicken the sauce as they are beaten.
Sugar
Sweetens the sauce and helps beat the yolks to a light, thick texture.
Hot milk
Adds moisture and loosens the mixture into a pourable sauce.
Egg whites
Whipped into foam, they make the sauce light and airy.

The step that matters

Fold in the beaten egg whites gently. The whites hold air in a fragile foam. Stirring or beating vigorously collapses the bubbles, so the sauce turns dense and loses its lightness.
