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 ↓

Ingredients
Directions
Make the custard
In a large pot, combine milk, eggs, sugar, and salt.
Cook over low heat, stirring constantly, until the mixture thickens but does not curdle.
Cool and flavor
Remove from heat and let it cool completely.
Once cooled, stir in the heavy cream and your choice of flavoring extract.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they cook gently, giving the base body and richness.
- Milk
- Forms the liquid base of the custard and carries the sweetness and flavor.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the finished ice cream softer.
- Heavy cream
- Adds fat, which makes the ice cream smooth and rich in texture.
The step that matters
Cook the custard gently until it thickens but does not curdle. Egg proteins set at moderate heat and curdle if overheated, leaving a grainy texture. Stirring constantly and keeping the heat low spreads heat evenly and keeps the custard smooth.
