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 ↓
Baked Chocolate Custard
Ingredients
Directions
The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard base
Heat the milk in a double boiler or on an asbestos mat.
In a separate bowl, mix the chocolate and sugar, then add the boiling water and stir until smooth and glossy.
Remove from heat and gradually beat in the hot milk.
Add the salt and pour the mixture over the well-beaten eggs, stirring continuously.
Bake and serve
Pour into a baking dish and place it in a pan of hot water.
Bake in a moderate oven at 350°F (175°C) until the center is firm, about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, giving it a firm, sliceable structure.
- Milk
- Provides the liquid base and moisture that gives the custard its smooth, creamy body.
- Sugar
- Sweetens the custard and balances the bitterness of the chocolate.
- Grated chocolate
- Supplies the chocolate flavor and color, and adds richness to the custard.
The step that matters
Gradually beat the hot milk into the chocolate mixture. Adding hot milk all at once can cause the chocolate to seize or stay grainy. Adding it slowly lets the mixture blend smoothly and stay glossy.
