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 ↓

Ingredients
Directions
Make the base
Scald the milk in a saucepan but do not boil it.
In a separate bowl, whisk the egg whites until stiff peaks form.
In another bowl, combine the egg yolks, sugar, and cornstarch.
Gradually add the scalded milk to the egg mixture, stirring constantly.
Finish and freeze
Combine the milk mixture with the whipped cream.
Add the vanilla or lemon extract for flavor.
Freeze the mixture until solid.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Provides the liquid base and creamy body of the ice cream.
- Egg yolks
- Thicken the custard and add richness through their emulsifying fats.
- Sugar
- Sweetens the base and lowers the freezing point so the ice cream stays scoopable.
- Cornstarch
- Stabilizes the custard and helps prevent it from becoming grainy or icy.
- Cream
- Adds fat for a smooth, rich texture that resists ice crystals.
The step that matters
Gradually add the scalded milk to the egg mixture, stirring constantly.. Adding hot milk too quickly or without constant stirring can scramble the egg yolks, leaving lumps instead of a smooth custard. Gradual addition warms the yolks gently so they thicken evenly.
