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
Scald the milk with the ground coffee.
In a separate bowl, mix the sugar, flour, and salt, then add the slightly beaten egg.
Gradually pour the hot coffee mixture into the egg mixture, stirring constantly.
Cook over hot water for 20 minutes, stirring occasionally.
Finish and freeze
Cool the mixture, then add the cream and vanilla.
Strain through a double thickness of cheesecloth and freeze.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the custard as it cooks and sets it into a smooth base.
- Flour
- Stabilizes the custard and helps it stay thick and smooth.
- Sugar
- Adds sweetness and softens the texture of the frozen ice cream.
- Cream
- Adds fat, giving the ice cream a rich, creamy mouthfeel.
- Milk
- Provides milk solids and liquid that form the body of the custard.
- Ground coffee
- Infuses the milk with the main coffee flavor of the ice cream.
The step that matters
Add the hot coffee mixture to the egg gradually. Pouring hot liquid into the egg too fast can scramble it before the custard thickens. Adding it slowly while stirring constantly warms the egg gently so the custard stays smooth.
