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
Beat the eight yolks and two whites of the eggs until light.
Boil the milk.
When boiling, stir in the chocolate, sugar, and eggs.
Pour the mixture into a clear pitcher.
Place the pitcher in a pot of boiling water.
Stir gently in one direction until it thickens to a cream.
Strain when cold.
Add the vanilla.
Pour into cups.
Top and serve
Beat the remaining egg whites to a stiff froth.
Sweeten to taste and beat well.
Top each cup with some of the froth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they gently set, and their whites whip into a light topping.
- Milk
- Forms the liquid base that the eggs thicken into a custard.
- French chocolate
- Provides the main chocolate flavour and colour of the custard.
- White sugar
- Sweetens the custard.
- Vanilla
- Adds aroma to the custard.
The step that matters
Stirring gently in the water bath. Eggs thicken as they heat, but high or uneven heat can scramble them and make the custard grainy. Stirring gently in one direction and keeping the water boiling, not the custard, helps it set smoothly into a cream.
