Why it works: Cream and sugar 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
- Egg yolks
- Thicken the cream into a smooth custard base and add richness to the ice cream.
- Cream
- Provides fat that gives the frozen ice cream a smooth, rich texture.
- Whole coffee
- Supplies the coffee flavor that defines the finished ice cream.
- Sugar
- Adds sweetness and softens the texture of the frozen ice cream.
The step that matters
Heating the custard base. Stirring constantly while heating keeps the egg yolks from scrambling. Egg proteins coagulate around 160°F, so overheating turns the base grainy and lumpy, which straining can only partly fix.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
