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 custard
In a saucepan, combine milk, 2 cups sugar, eggs, and salt.
Mix flour with a little cold water until smooth, then add to the mixture.
Cook over medium heat, stirring constantly, until thickened.
In a separate pan, brown 1 cup sugar until caramelized, then add to the custard.
Cook for an additional 5 minutes, then cool the mixture.
Finish and freeze
Once cooled, stir in the heavy cream and vanilla flavoring.
Freeze the mixture until solid.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins thicken the custard as they heat, giving the base body and a creamy texture.
- Milk
- Provides the liquid base and moisture that the custard and ice cream are built on.
- Heavy cream
- Adds fat, which makes the frozen ice cream smoother and richer in texture.
- Sugar
- Adds sweetness and, once browned, caramel flavor; it also softens the frozen texture.
- Flour
- Starch swells when heated with liquid, helping thicken the custard.
The step that matters
Cooking the custard until thickened. Stirring constantly over medium heat keeps the egg and flour mixture from scorching or lumping, and the custard must thicken fully so it sets smooth when frozen.
