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
- Yolk proteins thicken the custard as it cooks, giving the ice cream body.
- Flour
- Starch thickens the custard base and helps it stay smooth.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer.
- Cream
- Adds fat, which makes the ice cream rich and creamy in texture.
- Milk
- Provides the liquid base that the custard is built on.
The step that matters
Cook the mixture over low heat, stirring constantly. Gentle, constant stirring keeps the egg from scrambling while the custard thickens evenly. High heat or neglect can curdle the egg and leave lumps.
