Why it works: Vanilla and milk 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 base and add richness as they set with gentle heat.
- Cream
- Adds fat and richness, giving the frozen ice cream a smooth, creamy texture.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer.
- Milk
- Provides the liquid base that the sugar and yolks are dissolved and set into.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
The step that matters
Incorporating the egg yolks over low heat. If the heat is too high or stirring stops, the yolk proteins can scramble and curdle the custard. Constant stirring over low heat lets them thicken it smoothly.
