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 that sets into a creamy custard as it cooks.
- Egg yolks
- Thicken the custard and give it richness and structure as the proteins set.
- Granulated sugar
- Adds sweetness and helps the chocolate dissolve fully into the milk.
- Grated chocolate
- Provides the main chocolate flavour and colour of the custard.
- Egg white
- Whipped into a foam for the meringue topping, giving it lift and a light texture.
The step that matters
Bake until set. Overbaking tightens the egg proteins so they squeeze out liquid, leaving a grainy, weeping custard. The centre should still wobble slightly, as it firms further while cooling.
