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
- Coffee
- Provides the main coffee flavor and most of the liquid in the base.
- Milk
- Adds creaminess and softens the coffee's bitterness.
- Cream
- Adds richness and fat, giving a smoother texture after freezing.
- Castor sugar
- Sweetens the drink and lowers the freezing point, keeping it softer.
The step that matters
Freeze the mixture until it reaches the consistency of thick cream. Freezing without stirring can form hard ice crystals. Sugar and fat in the mixture lower the freezing point and soften the texture, so the drink should be checked for a thick, spoonable consistency rather than left to freeze solid.
