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 ↓

Allow to cool, then spread a layer of whipped cream on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the filling as it cooks into a set, creamy custard.
- Egg
- Listed in the ingredients but not used in the method, so its role is not stated.
- Chocolate
- Provides the chocolate flavour and colour of the filling.
- Sugar
- Sweetens the filling and balances the bitterness of the chocolate.
- Milk
- Forms the liquid base of the filling that thickens when heated.
The step that matters
Cook the filling until it thickens. Flour starch only thickens fully once the mixture is hot enough and stirred constantly; stopping early leaves a runny filling, while overcooking can scorch the milk and chocolate on the pan bottom.
