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 double boiler or in a can set inside a kettle of water, but do not boil.
Beat the yolks of the eggs well, add the sugar, and beat again.
Whip the egg whites until stiff and fold them into the yolk and sugar mixture.
Pour the hot milk into the egg mixture a little at a time, stirring constantly.
Return the mixture to the can and cook until it thickens like boiled custard.
Finish and churn
Strain the mixture through a sieve, let it cool, then add the cream and vanilla.
Pour the mixture into an ice cream freezer and churn according to the manufacturer's instructions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard as they cook, while whipped whites add lightness and air.
- Milk
- Forms the liquid base that the egg custard thickens into a smooth mixture.
- Cream
- Adds fat, which makes the frozen ice cream rich and smooth in texture.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer.
The step that matters
Cooking the custard. Heat must be gentle and the mixture must be stirred constantly. Egg yolks can scramble if they get too hot, leaving lumps instead of a smooth, thickened custard.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
