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 and supplies creaminess once frozen.
- Flour
- Thickens the milk so the custard becomes smooth and body-rich.
- Egg yolks
- Thicken the custard as they heat and add richness and smoothness.
- Egg whites
- Whipped into foam to trap air, giving the ice cream a lighter texture.
- Cream
- Adds fat, which keeps the frozen texture soft and rich.
- Sugar
- Adds sweetness and keeps the frozen ice cream from becoming too hard.
The step that matters
Heating the custard after adding the yolks. Egg yolks set at about 160°F and can curdle or scramble if overheated. Stirring constantly and not letting it boil keeps the custard smooth and thickened.
