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
- Egg yolks
- Thicken the custard and add richness as they set with gentle heat.
- Corn starch
- Thickens the milk mixture into a smooth, glossy filling as it heats.
- Grated chocolate
- Provides the chocolate flavour and some body to the filling.
- Milk
- Forms the liquid base that the starch and yolks thicken.
The step that matters
Cook over simmering water, stirring constantly. Egg yolks can curdle or scramble if overheated, and cornstarch needs to reach a simmer to thicken fully. Gentle, constant stirring over indirect heat keeps the filling smooth.
