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 so it holds its shape when cooled.
Egg whites
Whipped into foam, they lighten the mixture and give it an airy, spongy texture.
Sugar
Sweetens the citrus juice and balances its acidity.
Orange juice
Provides the main flavour and liquid base of the dish.

The step that matters

Folding in the egg whites. Egg whites should be beaten to stiff peaks and folded in only when the mixture is cool. If the mixture is still warm, it can deflate the foam, and if it is not yet thickening, the gelatine may not hold the airy structure.

Swap the orange

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

  1. Vanillafits better
  2. Raspberryfits about as well
  3. Orangethe original
  4. Raisinfits less well

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