Chocolate Custard

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the custard

  1. In a saucepan, mix the grated chocolate, sugar, flour, vanilla, and cold water.

  2. Cook over medium heat, stirring constantly, until the mixture thickens.

  3. Remove from heat and stir in the egg yolks.

Top and bake

  1. Beat the egg whites until stiff peaks form and spread over the custard.

  2. Bake in a moderate oven at 350°F (175°C) until the meringue is lightly browned.

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

What each ingredient does

Grated chocolate
Provides the chocolate flavor and color of the custard.
Flour
Thickens the custard as it cooks with the liquid.
Sugar
Sweetens the custard and helps the meringue brown.
Egg yolks
Thicken the custard and add richness when stirred in off the heat.
Egg whites
Whipped into stiff peaks to form the meringue topping that sets and browns in the oven.

The step that matters

Stirring the custard while it cooks. Constant stirring over medium heat keeps the starch from settling and scorching on the bottom, so the mixture thickens smoothly without lumps.
