Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. 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 flavour and aroma of the drink.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the drink softer when frozen.
- Cream
- Adds fat for richness and a smooth, creamy mouthfeel.
The step that matters
Freezing until just liquid enough to pour. Freezing fully makes the drink hard and icy, while stopping too early leaves it thin. Sugar and fat lower the freezing point, so the mixture stays partly liquid and forms a fine, scoopable slush when partly frozen.
