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 base
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 smooth.
Gradually add the scalded milk to the egg mixture, stirring constantly.
Finish and freeze
In another bowl, whip the egg whites until stiff peaks form.
Combine the milk mixture with the whipped cream and fold in the whipped egg whites.
Add vanilla or lemon extract to taste, then freeze the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify and thicken the base into a smooth, rich custard.
- Egg whites
- Whipped to stiff peaks, they add air and a light, airy texture.
- Cream
- Adds fat for a smooth, creamy mouthfeel and a soft texture after freezing.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer.
- Corn-starch
- Stabilizes the custard and helps prevent large ice crystals from forming.
The step that matters
Gradually add the scalded milk to the egg mixture, stirring constantly.. Adding hot milk too quickly can scramble the egg yolks, leaving lumps. Adding it slowly while stirring gently tempers the yolks so the custard thickens smoothly.
