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
Beat the eggs until very light.
Rub the chocolate smooth in a little milk.
Heat the milk almost to boiling.
Gradually pour the hot milk into the beaten eggs and sugar, stirring constantly.
Stir in the chocolate mixture and return to the kettle.
Heat until the mixture thickens, stirring constantly.
Remove from heat and let cool.
Finish and freeze
Once cool, add the vanilla and cream, then freeze.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard base and add richness as they set with gentle heat.
- Sugar
- Sweetens the base and helps keep the frozen ice cream smooth and soft.
- Cream
- Adds fat for a rich, smooth texture that resists iciness.
- Whole milk
- Forms the liquid base of the custard and adds body.
- Chocolate
- Provides the main flavor and color, and its fat adds smoothness.
The step that matters
Pour the hot milk into the eggs gradually while stirring. Adding hot liquid too fast can scramble the eggs into lumps. Gradual addition with constant stirring tempers them so the custard thickens evenly.
