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
- Cornstarch
- Thickens the milk mixture into a smooth, sliceable custard as it cooks.
- Egg yolk
- Adds richness and helps set the custard as it cooks.
- Sugar
- Sweetens the filling and balances the bitterness of the chocolate.
- Baker's chocolate
- Provides the chocolate flavor and deep color of the filling.
- Milk
- Forms the liquid base that thickens into the custard.
The step that matters
Cook the filling until thickened. Cornstarch needs to reach a simmer over medium heat to swell and thicken fully. Undercooked starch leaves the filling thin and runny, and it may not set when cooled.
