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

What each ingredient does

Eggs
Egg yolks thicken the custard as they set with heat, and whites add lightness.
White sugar
Sweetens the custard and helps keep the yolks smooth while they are mixed.
Chocolate
Provides the main flavor and, once dissolved, the rich color of the custard.
Heavy cream
Adds fat, which gives the custard a smooth, rich texture.

The step that matters

Pour the hot mixture over the egg mixture, stirring constantly. Egg proteins set at around 70°C and can scramble if hot liquid hits the yolks too fast or unstirred. Constant stirring spreads the heat evenly so the custard thickens smoothly.
