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

What each ingredient does

Gelatin
Sets the liquid into a light, wobbly structure that holds the whipped foam.
Egg whites
Whipped into foam, they trap air and give the dessert its light, sponge-like texture.
Orange juice
Supplies the flavour and liquid that the gelatin sets into the sponge.
Sugar
Sweetens the juice and helps stabilise the whipped egg white foam.

The step that matters

When cold, add the egg whites and whisk until light.. The gelatin must be cool and just beginning to thicken before the whites go in. If it is still warm, it deflates the foam; if it has set, the whites will not blend evenly, so the airy texture is lost.

Swap the orange

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