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 ↓
Philadelphia Coffee Ice Cream
Ingredients
Directions
Make the coffee base
Grind the coffee coarsely.
Combine the ground coffee with 2 cups of cream in a saucepan over medium heat and heat without boiling for 10 minutes.
Strain the mixture through a fine sieve, pressing to extract all the coffee flavor.
Add the powdered sugar to the strained mixture and stir until dissolved.
Freeze and serve
Once the mixture is completely cold, add the remaining 2 cups of cream.
Freeze the mixture according to your ice cream maker's instructions.
After freezing, pack the ice cream and let it sit for 2 hours before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Provides fat and richness, giving the ice cream a smooth, creamy body.
- Powdered sugar
- Adds sweetness and softens the texture by lowering the freezing point.
- Coffee
- Supplies the main coffee flavor, extracted into the warm cream.
The step that matters
Cool the mixture completely before adding the remaining cream. Adding cream to a warm base slows cooling and can cause a grainy or icy texture, because large ice crystals form when the base freezes slowly. Chilling it fully first gives a smoother result.
