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 caramel custard
Melt 1 cup of sugar in a skillet until it turns into a brown syrup.
Add the heated milk to the syrup.
In a bowl, cream together the egg yolks, 1 cup of sugar, and corn starch.
Stir the creamed mixture into the milk and syrup, and let it boil while stirring constantly.
If the mixture is lumpy, strain it through a sieve.
Finish and freeze
Fold in the beaten egg whites once the mixture is cold.
Add the cream and vanilla extract, then freeze the mixture.

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 add lightness when folded in.
- Corn starch
- Thickens the custard so it holds a smooth, scoopable body.
- Sugar
- Sweetens the base and browns to a caramel flavor when melted.
- Milk
- Forms the liquid base of the custard.
- Cream
- Adds fat for a richer, smoother texture in the frozen result.
The step that matters
Stirring the custard while it boils. Starch thickens only when it boils, and constant stirring prevents scorching on the bottom and lumps forming. Lumps that remain can be strained out.
