Why it works: Sugar and chocolate are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
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
In a saucepan, combine sweet milk, sugar, egg yolks, flour, and chocolate.
Cook over medium heat, stirring constantly until thickened.
Pour the mixture into a baked pie crust.
Top and bake
Beat the egg whites until stiff peaks form, then fold in 1 tablespoon of sugar.
Spread the meringue over the custard.
Bake in a preheated oven at 350°F (175°C) until the meringue is golden brown.

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 and add richness as they set with heat.
- Flour
- Thickens the milk mixture so the custard holds its shape when sliced.
- Egg whites
- Whipped into a meringue that forms the light topping and browns in the oven.
- Chocolate
- Provides the chocolate flavour and colour of the custard.
- Sugar
- Sweetens the custard and, in the meringue, stabilises the whipped whites.
The step that matters
Cooking the custard until thickened. Stir constantly over medium heat so the egg yolks and flour thicken evenly without scorching or curdling. Undercooked custard stays runny and will not set properly once baked under the meringue.
