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

What each ingredient does

Egg
Yolk thickens and enriches the custard, while the whipped white adds lightness and structure.
Milk
Provides the liquid base that the egg proteins thicken and set into a gruel.
Sugar
Adds sweetness and helps stabilize the whipped egg white foam.
Lemon juice
Adds acidity that brightens flavor and helps stabilize the beaten egg white.

The step that matters

Pouring the heated milk while beating rapidly. Adding hot liquid to egg yolk can cause it to curdle or scramble in lumps. Beating rapidly disperses the heat evenly through the mixture so the egg thickens smoothly instead of setting in pockets.
