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 chocolate base
In a clean saucepan, combine the crushed chocolate and sugar.
Gradually pour in the milk while stirring continuously.
Bring the mixture to a boil, then reduce heat and let it simmer for 20 minutes, stirring occasionally.
Add the eggs
Separate the eggs, using the yolks of 4 and the whites of 3.
Mix the yolks and egg whites with the chocolate mixture, ensuring it is not too hot.
Strain the mixture through a fine strainer into a double boiler.
Thicken and serve
Stir continuously until the custard thickens, about 20 minutes after the water in the pan boils.
Remove from hot water and let it cool in the boiler.
Stir in 1 teaspoon of vanilla before serving in a glass dish or custard cups.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set when heated, thickening the milk mixture into a custard.
- Milk
- Forms the liquid base, providing moisture and a creamy texture.
- Chocolate
- Supplies the main flavour and richness, along with cocoa fat.
- Sugar
- Adds sweetness and balances the bitterness of the chocolate.
The step that matters
Stir continuously until the custard thickens. Egg proteins set as they heat, so too much heat or stopping the stirring can scramble the eggs into lumps. Gentle, constant stirring keeps the custard smooth and evenly thickened.
