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 ↓
Ice Cream
Ingredients
Directions
Make the custard
Scald the milk in a saucepan, but do not boil.
In a separate bowl, whisk the egg yolks with the sugar and corn‑starch until well combined.
Gradually add the scalded milk to the egg mixture, stirring constantly.
Add cream and freeze
In another bowl, whip the egg whites until stiff peaks form, then fold them into the cream.
Combine the milk mixture with the whipped cream, add flavoring, and mix well.
Freeze the mixture until firm.

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 gives the ice cream its body and dairy flavour.
- Egg yolks
- Emulsify the mixture and thicken the custard as they gently heat, adding richness.
- Sugar
- Adds sweetness and keeps the frozen texture softer and easier to scoop.
- Corn-starch
- Thickens the custard base so the finished ice cream is smoother and less icy.
- Cream
- Adds fat, which makes the ice cream rich and creamy on the palate.
The step that matters
Gradually add the scalded milk to the egg mixture, stirring constantly.. Adding hot milk slowly and stirring keeps the egg yolks from heating too fast and scrambling. Gentle, gradual warming lets the custard thicken smoothly instead of turning lumpy.
