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

What each ingredient does

Gelatin
Sets with the liquid to give the ice a firm, smooth body.
Sugar
Adds sweetness and softens the frozen texture so it is less icy.
Orange juice
Provides the main flavour and fruity aroma of the ice.
Lemon juice
Adds acidity that brightens the sweetness and sharpens the citrus flavour.

The step that matters

Add the juice only once the syrup is cool. Heat dulls the fresh aroma and flavour of citrus juice, so adding it after the sugar syrup has cooled keeps the orange and lemon taste bright.

Swap the lemon

How well each one fits the dish's main ingredients (orange, sugar, gelatin):

  1. Vanillafits better
  2. Lemonthe original
  3. Mangofits about as well
  4. Figfits about as well

Fit is the average pairing score against orange, sugar, gelatin. Candidates are from the same food group and used in at least 100 recipes.
