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
In a saucepan, combine the milk, egg yolks, sugar, and grated chocolate.
Cook over medium heat, stirring constantly, until the mixture thickens.
Remove from heat and let it cool slightly, then add vanilla for flavor.
Pour the custard into cups.
Top and serve
Beat the egg whites until stiff, then fold in powdered sugar.
Spoon the egg white mixture on top of the custard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set during gentle cooking, giving it a rich, smooth body.
- Milk
- Forms the liquid base that the yolks thicken into a creamy custard.
- Egg whites
- Whipped until stiff, they form a light, airy topping that sits over the custard.
- Grated vanilla chocolate
- Adds chocolate flavor and color to the custard base.
- Sugar
- Sweetens the custard and helps balance the chocolate.
The step that matters
Cook the custard until it thickens. Egg yolks thicken when gently heated, but if the heat is too high or they are not stirred constantly, they can scramble and turn grainy. Stop cooking once the mixture coats a spoon.
