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

What each ingredient does

Unflavoured gelatine
Provides the structure that lets the juice mixture set into firm squares when chilled.
Orange juice
Supplies most of the liquid and the main citrus flavour.
Grapefruit juice
Adds liquid and a tart, bitter citrus note that balances the sweetness.
Sugar
Sweetens the juice and softens the sharpness of the citrus.

The step that matters

Chill until partially set. Gelatine sets as it cools, so the mixture should be firm enough to hold its shape but still soft. Chilling too briefly leaves squares that will not hold together, while chilling too long makes them rubbery and hard to cut cleanly.

Swap the walnut

The recipe marks walnut as optional. How well each one fits the dish's main ingredients (grapefruit, orange, sugar):

  1. Almondfits better
  2. Walnutthe original
  3. Pistachiofits about as well
  4. Hazelnutfits about as well

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