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

What each ingredient does

Milk
Forms the liquid base that thickens into a custard when heated with the yolks.
Egg yolks
Thicken the sauce as they set with heat, giving it a smooth, custard-like body.
Powdered sugar
Sweetens the sauce and dissolves easily into the warm milk mixture.
Egg whites
Whipped and folded in at the end, they add lightness and an airy texture.

The step that matters

Stirring the yolks into the boiling milk. Egg yolks thicken as their proteins set with heat. If the mixture is added too fast or stirred too little, the yolks can curdle or form lumps. Keep stirring steadily until the sauce coats a spoon.
