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

What each ingredient does

Egg yolks
Thicken the custard as they cook and add richness to its texture.
Egg whites
Whipped to stiff peaks, they lighten the custard and add airy volume.
Vanilla chocolate
Provides the chocolate flavor and color of the custard.
Granulated sugar
Sweetens the custard and helps the egg yolks blend smoothly.
Sweet milk
Forms the liquid base that carries the chocolate and sets into the custard.

The step that matters

Return the mixture to the heat and cook until thickened, stirring frequently.. Egg proteins set as they heat, so cooking too hard or without stirring can scramble the eggs and leave lumps. Stop once the custard coats a spoon.
