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 ↓

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 of the custard that the other ingredients set into.
- Egg yolks
- Thicken the custard and add richness through their emulsifying fats and proteins.
- Sugar
- Adds sweetness and softens the frozen texture by lowering the freezing point.
- Cream
- Adds fat, which makes the ice cream smooth and rich.
- Egg whites
- Whipped into foam, they add air that lightens the texture of the ice cream.
- Flour
- Thickens the milk mixture so the custard holds body before adding the yolks.
The step that matters
Return the custard to heat without boiling. Egg yolks thicken as they warm, but if the custard boils they can scramble, leaving lumps and a grainy texture. Stir constantly and heat only 1-2 minutes.
