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 heat and set, giving it a rich, smooth body.
Milk
Forms the liquid base of the custard, carrying the chocolate and setting with the eggs.
Sweet chocolate
Provides the chocolate flavour and colour that define the custard.
Powdered sugar
Sweetens the custard and dissolves smoothly into the warm base.
Egg whites
Beaten whites folded in add lightness and airy texture to the custard.

The step that matters

Heating the egg yolks. Egg yolks thicken the custard only as they gently heat and set. If the mixture is overheated or boils hard after the yolks go in, they can scramble and leave the custard grainy, so heat it just to the point of thickening.
