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

What each ingredient does

Butter
Provides richness and a smooth, creamy body when creamed with sugar.
Sugar
Sweetens the sauce and helps create a smooth texture when creamed with butter.
Egg white
Whipped stiff, it lightens the sauce and gives it an airy, soft texture.

The step that matters

Gently fold in the beaten egg white. Stiff whipped egg white holds air in the mixture. Vigorous stirring deflates it, making the sauce dense rather than light and fluffy.

Swap the lemon

How well each one fits the dish's main ingredients (butter, sugar, cream, egg, nutmeg, vanilla, wine):
