Why it works: Chocolate and sugar 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 Custards
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the custard
Scald the milk in a saucepan.
Add the grated chocolate and sugar to the milk, stirring until dissolved.
In a bowl, beat the egg yolks.
Mix the cornstarch with a little cold milk and add it to the egg yolks.
Pour the chocolate milk mixture over the egg yolks and return to the heat.
Cook while stirring constantly until thickened, about 5 minutes.
Finish and serve
Let the mixture cool, then add any desired flavoring and pour into small glasses.
Beat the egg whites until stiff, then fold in the powdered sugar and heap on top of the custards.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the custard sets into.
- Cornstarch
- Thickens the custard as its starch swells when heated.
- Eggs
- Yolks thicken the custard as proteins set; whites form the light, stiff topping.
- Chocolate
- Provides the main flavor and richness of the custard.
- Sugar
- Adds sweetness and dissolves into the warm milk.
The step that matters
Cook while stirring constantly until thickened. Egg yolks can curdle or scramble if overheated, and the starch can scorch on the bottom. Constant stirring spreads heat evenly so the custard thickens smoothly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
