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

What each ingredient does

Egg whites
Whipped into stiff peaks, they trap air and give the dessert its light, airy texture.
Gelatin
Sets the orange juice into a firm, sliceable structure as it cools.
Orange juice
Provides the liquid base and the citrus flavor that the dessert is built around.
Sugar
Adds sweetness to balance the tartness of the orange juice.

The step that matters

Folding the egg whites into the orange juice mixture. Stirring or folding too vigorously knocks the air out of the whipped egg whites, which makes the dessert dense instead of light. Fold gently, just until no streaks of white remain.

Swap the orange

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

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

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