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

What each ingredient does

Gelatine
Sets the liquid mixture into a light, wobbly texture once it cools.
Egg whites
Whipped and folded in, they add air and a light, spongy texture.
Sugar
Sweetens the mixture and adds body to the orange base.
Orange juice
Provides the main flavour and liquid, with acidity giving a bright tang.

The step that matters

Gently fold in the beaten egg whites. Egg white foam holds air that gives the dessert its lightness. Stirring vigorously or folding into a mixture that is too cold or too set can knock out that air or leave lumps, so the texture turns dense.

Swap the orange

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

  1. Vanillafits better
  2. Raisinfits better
  3. Lemonfits better
  4. Orangethe original

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