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 as they set with gentle heat, giving it a rich texture.
- Egg white
- Adds protein that helps the custard set and gives it a lighter body.
- Milk
- Provides the liquid base that the eggs thicken into a smooth custard.
- Loaf sugar
- Sweetens the custard and adds body to its flavour.
The step that matters
Stirring over the heat without boiling. Egg proteins thicken gently as they warm; if the custard boils, they scramble and turn grainy, so it must stay below boiling while it thickens.
