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 in the steps was added when the recipe was transcribed, as a starting point.
Make the custard
Dissolve the chocolate with a little milk, then add half the sugar and the remaining milk.
Heat the mixture in a double boiler until hot.
Pour the hot mixture over the beaten eggs and the rest of the sugar. Add the vanilla.
Bake
Bake in a moderate oven (350°F / 175°C) until set, like custard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a firm, sliceable texture as they coagulate with heat.
- Milk
- Provides the liquid base and moisture that the eggs set into a creamy custard.
- Sugar
- Adds sweetness and balances the bitterness of the chocolate.
- Chocolate
- Supplies the main flavor and dark color of the custard.
The step that matters
Baking until set. Eggs thicken as their proteins coagulate with heat, so the custard must be baked just until set. Overbaking causes the proteins to tighten too far, making the custard grainy and weeping liquid.
“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.
