Directions
Make the custard
In a large pot, combine the cream and egg yolks with the strong coffee.
Heat the mixture over low heat, stirring until hot but not boiling.
Remove from heat and stir in the vanilla extract and powdered sugar until well mixed.
Freeze and serve
Pour the mixture into a can and pack it with ice.
Let it set for several hours, preferably overnight, before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help emulsify the cream and coffee into a smooth base.
- Cream
- Provides fat for a rich, smooth texture.
- Powdered sugar
- Adds sweetness and softens the frozen texture.
- Strong coffee
- Supplies the main flavor, with a roasted, slightly bitter note.
- Vanilla extract
- Adds aroma that rounds out the coffee flavor.
The step that matters
Heat gently without boiling. Egg yolks thicken as they warm, but if the mixture gets too hot it can curdle or scramble. Stirring over low heat keeps the custard smooth and well emulsified.
