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 ↓
Coffee Ice Cream
Ingredients
Directions
Make the custard
Combine the heavy cream and egg yolks in a saucepan to make a custard.
Add the hot Mocha coffee berries to the custard.
Cover the pan with a lid and a napkin to trap steam.
Let the custard sit for 1 hour.
Strain the custard and sweeten it with sugar.
Once the custard is cold, pour the mixture into a freezing pot.
Make the coffee infusion
Place 2 ounces of ground coffee in a French cafetiere.
Pour ½ cup boiling water over the ground coffee.
Allow the infusion to run through.
Boil the infusion.
Add 2 more ounces of coffee to the infusion.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heavy cream
- Provides fat and richness, giving the ice cream a smooth, creamy body.
- Egg yolks
- Thicken the custard and add richness and emulsifying fat for a smooth texture.
- Ground coffee
- Supplies the coffee flavour and aroma that defines the ice cream.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer.
The step that matters
Let the custard sit covered for 1 hour. Covering traps steam so the hot coffee flavour infuses the cream evenly and the custard keeps its moisture. Letting it cool fully before freezing helps the texture stay smooth rather than icy.
“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.
