Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. 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
Heat the milk and whisk in the egg yolks to prepare a soft custard.
Dissolve the chocolate in ½ cup of warm milk and heat to boiling.
Once cool, sweeten the chocolate mixture with brown sugar and add vanilla.
Combine the chocolate mixture with the custard and pour into a dish.
Top and bake
Beat the egg white until stiff, adding a little sugar, and spread over the top.
Brown slightly in a 350°F (175°C) oven and serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the milk into a soft custard as they set with gentle heat.
- Egg white
- Beaten stiff, it forms a light meringue topping that browns in the oven.
- Unsweetened chocolate
- Provides the chocolate flavor and color of the custard.
- Milk
- Forms the liquid base of the custard, giving it body and moisture.
- White sugar
- Sweetens the meringue topping and helps it hold its stiff structure.
The step that matters
Heating the egg yolks in the milk. Egg yolks set into custard only with gentle heat. If the mixture gets too hot, the yolks can scramble and turn grainy, so the custard should be cooked slowly and stirred.
“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.
