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 ↓
Chocolate Ice Cream
Ingredients
Directions
Make the custard
Heat the milk in a saucepan and add the sugar, corn starch, and chocolate dissolved in a little of the milk.
Beat the egg and add it to the milk mixture, stirring constantly until thick.
Remove from heat and stir in the cream.
Finish and freeze
Once cooled, add vanilla to taste and freeze the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the milk mixture as it heats, giving the base body and a custard-like texture.
- Corn starch
- Thickens the milk mixture so it becomes smooth and stable when cooled and frozen.
- Sugar
- Sweetens the base and lowers its freezing point, keeping the ice cream softer.
- Rich cream
- Adds fat for a smooth, rich mouthfeel and softer texture.
- Chocolate
- Provides the main flavor and color of the ice cream.
The step that matters
Adding the egg while stirring constantly. If the hot milk is added to the egg too quickly or stirring stops, the egg can scramble and form lumps. Constant stirring keeps the egg proteins evenly dispersed as the mixture thickens smoothly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
