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 ↓
Caramel Ice Cream
Ingredients
Directions
Make the custard
Heat the milk in a saucepan until it reaches boiling point.
In a bowl, beat the eggs with the sugar.
Pour half of the hot milk over the egg mixture and stir well.
Return the mixture to the saucepan and add the remaining milk and cornstarch mixed with a little cold milk.
Stir constantly until the mixture thickens to a custard consistency.
Add the caramel and finish
In an iron frying pan, heat the brown sugar until it dissolves and becomes liquid, then pour it hot into the custard.
Once the custard is cool, stir in the vanilla extract and fold in the whipped heavy cream.
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
- Eggs
- Their proteins set when heated, thickening the custard into a smooth base.
- Cornstarch
- Swells when heated with liquid, thickening the custard so it holds its body.
- Heavy cream
- Adds fat and richness, and whipped air gives the frozen ice cream a lighter texture.
- Brown sugar
- Caramelises when melted, adding deep toffee flavour and sweetness.
- Milk
- Forms the liquid base of the custard, providing moisture and dairy flavour.
The step that matters
Stirring the custard until it thickens. Egg proteins and cornstarch thicken the mixture as it heats, but if it is left unstirred or overheated the eggs can scramble and curdle, leaving lumps instead of a smooth custard.
