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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the custard filling.
- Egg yolks
- Thicken the custard and add richness when stirred into the hot mixture.
- Cornstarch
- Thickens the milk mixture into a smooth, sliceable filling as it heats.
- Grated chocolate
- Provides the chocolate flavour and deep colour of the filling.
- Egg whites
- Whipped into a foam that forms the light, airy meringue topping.
The step that matters
Adding the egg yolks off the heat. Egg yolks can scramble if they meet very hot liquid directly. Removing the pan from the heat before adding them, and stirring constantly, keeps the custard smooth while it thickens.
