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 ↓

Make the custard
Scald the milk with the ground coffee.
In a bowl, mix the sugar, flour, and salt, then add the slightly beaten egg.

Finish and freeze
Cool the mixture, then add the cream and vanilla.
Strain through a double layer 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, giving the ice cream a smooth, rich body.
- Milk
- Forms the creamy base that carries the coffee flavor and softens the texture.
- Thin cream
- Adds fat for a smooth, rich mouthfeel and keeps ice crystals small.
- Sugar
- Sweetens the base and lowers the freezing point for a softer scoop.
- Flour
- Stabilizes the custard so it thickens without curdling during cooking.
The step that matters
Cooking the custard over hot water. The egg mixture must thicken gently. Overheating can scramble the egg and make the base grainy, so stir steadily and keep the water below a hard boil.
