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
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.
Cool the chocolate mixture, sweeten with brown sugar, and add vanilla extract.
Pour the chocolate mixture into a dish.
Top and serve
Beat the egg white until stiff, adding a little sugar, and spread over the chocolate.
Brown the top slightly in the oven.
Serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baker's chocolate
- Provides the chocolate flavour and colour of the custard.
- 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.
- Milk
- Forms the liquid base of the custard and dissolves the chocolate.
- Brown sugar
- Sweetens the chocolate mixture and adds a light caramel note.
The step that matters
Cooling the chocolate mixture before adding the egg whites. The custard must be cooled before the meringue is spread over it, so the topping stays light instead of deflating or weeping. Overheated egg yolks can also curdle, so heat the custard gently.
