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 it.
In a bowl, whisk the egg yolks with the sugar and cornstarch until smooth.
Gradually add the scalded milk to the egg mixture, stirring constantly.
Fold and freeze
In a separate bowl, whip the egg whites until stiff peaks form.
Fold the whipped egg whites into the cream.
Combine the milk mixture with the whipped cream, add flavoring, and freeze.

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 and adds dairy richness and creamy texture.
- Egg yolks
- Enrich the base and help thicken it as it sets, adding richness.
- Sugar
- Adds sweetness and softens the texture of the frozen ice cream.
- Cornstarch
- Thickens the custard base so it holds body and resists icy separation.
- Cream
- Adds fat for a smooth, rich texture in the finished ice cream.
- Egg whites
- Whipped to stiff peaks, they add air and a light, airy texture.
The step that matters
Adding the scalded milk to the yolks. Pour the hot milk in slowly while whisking constantly. Adding it too fast can scramble the egg yolks into lumps, leaving a grainy custard instead of a smooth base.
