Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the sour acidity and main citrus flavour of the ice.
- Sugar
- Adds sweetness and softens the ice, making it less hard when frozen.
- Oranges
- Add sweetness and a rounder citrus aroma from their juice and rind.
The step that matters
Let the syrup cool before adding the juice. Heat dulls the fresh aroma and bright flavour of citrus juice, so the syrup should be fully cooled before the juice goes in.
