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.
