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
Combine sweet milk, brown sugar, egg yolks, chocolate, and flour in a saucepan.
Cook over medium heat, stirring constantly until thickened.
Add the meringue and bake
Beat egg whites in a separate bowl until stiff peaks form, then gradually add sugar.
Fold the beaten egg whites into the chocolate mixture.
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.
