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 with the yolks of 5 eggs and 1 egg white to prepare a soft custard.
Make the chocolate layer
Dissolve the chocolate in ½ cup of warm milk and heat it to boiling point.
Once cool, sweeten the chocolate mixture with brown sugar and add vanilla extract.
Top and bake
Pour the chocolate mixture into a dish and cover with the beaten egg whites mixed with a little sugar.
Brown slightly in the oven and serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard as they set, giving it body and a smooth texture.
- Milk
- Forms the liquid base of the custard, giving it a soft, creamy body.
- Chocolate
- Supplies the main chocolate flavour and richness, and melts smoothly into warm milk.
- White sugar
- Sweetens the dish and the beaten egg white topping.
- Brown sugar
- Sweetens the chocolate mixture, adding a deeper, caramel-like flavour.
The step that matters
Heating the milk and yolks for the custard. Egg proteins set gently at moderate temperatures. If the mixture gets too hot or is heated too fast, the yolks can scramble and curdle instead of forming a smooth, soft custard. Stirring steadily and heating gently keeps it silky.
