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. Combine sweet milk, brown sugar, egg yolks, chocolate, and flour in a saucepan.

  2. Cook over medium heat, stirring constantly until thickened.

Add the meringue and bake

  1. Beat egg whites in a separate bowl until stiff peaks form, then gradually add sugar.

  2. Fold the beaten egg whites into the chocolate mixture.

  3. Pour into a baking dish and bake at 350°F (175°C) until set.

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 cook and add richness to the mixture.
Egg whites
Whipped into stiff peaks, they add airy lightness and help the custard set and rise.
Flour
Thickens the chocolate mixture so it holds its shape when cooked.
Brown sugar
Adds sweetness and a molasses flavour that complements the chocolate.
Chocolate
Provides the main chocolate flavour and colour of the custard.

The step that matters

Cook the custard until thickened. Stirring constantly over medium heat keeps the egg yolks and flour from scorching or lumping, and the mixture must thicken fully so it can hold the folded egg whites and set in the oven.
