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 ↓
Coffee Ice Cream
Ingredients
Directions
Make the custard
In a pan, combine the milk and sugar and bring to a boil.
Whisk the eggs and egg yolks until very light.
Pour the boiling milk over the egg mixture and mix well.
Return the mixture to the pan and stir over low heat until it thickens, but do not let it boil.
Strain the mixture and allow it to cool.
Flavour and freeze
Once cool, add the coffee essence and vanilla essence.
Pour the mixture into an ice cream maker and freeze according to the manufacturer's instructions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they thicken over gentle heat, giving the ice cream body and richness.
- Egg yolks
- Add fat and emulsifiers that make the custard smooth and rich, and help it thicken.
- Milk
- Forms the liquid base of the custard and carries the flavour and sweetness.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer and scoopable.
The step that matters
Stir over low heat without boiling. Egg proteins thicken the custard gently, but if it boils they scramble, leaving a grainy texture that straining can only partly fix.
