Ingredients
Directions
Make the base
Pound the coffee in a mortar until crushed but not powdered.
Combine the crushed coffee, milk, and sugar in a saucepan and bring to a boil.
Remove from heat and let it cool.
Strain the mixture over the egg yolks in a double boiler.
Make the custard
Stir over low heat until the custard thickens, being careful not to curdle it.
Once cool, fold in the whipped cream.
Freeze
Freeze the mixture in an ice cream maker.
Transfer to a mold and freeze until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set with gentle heat, giving the ice cream a rich, smooth body.
- Cream
- Adds fat and richness, giving a creamy texture and a softer, smoother bite.
- Milk
- Provides the liquid base that carries the coffee flavor and dissolves the sugar.
- Loaf sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer.
- Freshly roasted coffee
- Supplies the main aroma and flavor, infused into the milk as it heats.
The step that matters
Stirring the custard over low heat. Egg yolks thicken as they warm, but if the heat is too high they scramble and curdle. Gentle, constant stirring keeps the custard smooth and silky.
“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.
