Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sugar
Dissolves into the syrup to sweeten the frappe and lowers the freezing point, keeping the texture smoother.
Orange juice
Supplies the main orange flavour and some sweetness and acidity.
Lemon juice
Adds sharp acidity that brightens the orange flavour and balances the sugar.

The step that matters

Cool the mixture completely before freezing. A warm mixture takes longer to freeze, which lets larger ice crystals form and gives a coarse, icy texture. Chilling it first and straining out pulp helps produce a smoother frozen result.
