Make the coffee cream

  1. Grind the coffee coarsely.

  2. Combine the coffee with 1 pint of cream in a saucepan over medium heat and let it sit without boiling for 10 minutes.

  3. Strain the mixture through a fine sieve, pressing to extract all the coffee flavor.

  4. Add the powdered sugar and stir until dissolved.

Freeze and serve

  1. Once the mixture is completely cold, add the remaining pint of cream.

  2. Freeze the mixture according to your ice cream maker's instructions.

  3. 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 texture.
Powdered sugar
Sweetens the base and lowers its freezing point, keeping the ice cream softer.
Coffee
Supplies the main flavor and aroma of the ice cream.

The step that matters

Letting the coffee steep without boiling. Boiling can make coffee taste bitter and burnt, so the mixture should only sit warm over medium heat to extract flavor gently.
