Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cranberries
- Provide the tart fruit flavour and the bulk of the frappe's body.
- Sugar
- Sweetens the tart cranberries and lowers the freezing point so the frappe stays soft.
- Lemons
- Add acidity that brightens the cranberry flavour.
The step that matters
Add the sugar and boil until dissolved. Sugar must fully dissolve so it can dissolve evenly into the liquid. Undissolved sugar can leave grainy crystals, and the sugar content also controls how soft the frozen mixture stays.
