Chocolate Custard

Ingredients

Directions

Prepare

  1. Heat the milk in a double boiler.

  2. Grate the chocolate into a bowl.

Make the custard

  1. Add the sugar and egg yolks, then beat until creamy.

  2. When the milk starts to steam, gradually pour it into the chocolate mixture, stirring briskly to prevent lumps.

  3. Return the mixture to the double boiler and cook until thickened like cream.

Chill and serve

  1. Once cooled, pour into a glass dish.

  2. When cold, top with whipped cream before serving.

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 cook and help it set.
Milk
Forms the liquid base that the eggs thicken into a custard.
Sugar
Adds sweetness that balances the bitter chocolate.
Sweet chocolate
Provides the main chocolate flavor and color.

The step that matters

Adding the hot milk to the chocolate mixture. Pouring the hot milk in too quickly can scramble the egg yolks and cause lumps. Adding it gradually while stirring briskly warms the yolks slowly so the mixture blends smoothly.
