Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Powdered sugar
- Sweetens the custard and helps the egg yolks combine smoothly with the milk.
- Egg yolks
- Thicken the custard as they set gently with heat, giving it a rich, smooth body.
- Sweet cream
- Adds fat and richness, giving the frozen ice a creamy, smooth texture.
- Freshly-ground coffee
- Provides the main coffee flavour and aroma in the custard base.
- Roasted coffee berries
- Infuse the milk with roasted coffee flavour and aroma.
- Caster sugar
- Sweetens the coffee berry mixture and softens the frozen texture.
The step that matters
Stir gently until thickened, but do not boil. Egg yolks thicken as they heat, but past a certain temperature they scramble and curdle. Stirring gently over a moderate heat keeps the custard smooth.
