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 ↓

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 as they set with gentle heat, giving body and richness.
- Chocolate
- Provides the main flavor and adds fat that makes the ice cream smooth.
- Cream
- Adds fat that makes the ice cream rich and creamy rather than icy.
- Milk
- Forms the liquid base of the custard that the other ingredients are cooked into.
- Sugar
- Sweetens the custard and lowers the freezing point, keeping the texture softer.
The step that matters
Cook in a double boiler for five minutes. Egg yolks thicken gently as they heat, but too much heat can scramble them into lumps. A double boiler keeps the temperature low and even.
