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 ↓

Add the rest of the sugar to the corn starch mixture.
Finish the custard
Beat egg yolks with a spoonful of cold milk.
Stir the yolk mixture into the custard.
Cook until it thickens, but do not let it boil.

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 and whites whip into foam that lightens the ice cream.
- Milk
- Forms the liquid base that the starch and egg yolks thicken into custard.
- White granulated sugar
- Adds sweetness and helps stabilize the beaten egg whites.
- Corn starch
- Thickens the custard so the ice cream holds a smooth, body-rich texture.
- Vanilla extract
- Provides the dominant aroma and flavor of the finished ice cream.
The step that matters
Cook the custard until it thickens but does not boil. Egg yolks and starch thicken as they heat, but overheating can curdle the yolks and leave the custard grainy. Gentle heat keeps it smooth, and straining catches any small lumps.
“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.
