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

What each ingredient does

Bananas
Provide the main body, sweetness and moisture of the filling.
Egg whites
Whipped to stiff peaks, they lighten the filling and give it an airy texture.
Sugar
Sweetens the filling and helps draw moisture from the orange rind for flavour.
Whipped cream
An optional substitute for egg whites that adds richness and a soft, airy texture.

The step that matters

Whip the egg whites until stiff peaks form. Egg whites under-whipped stay runny and deflate the filling, while over-whipped whites turn grainy and dry. Stopping at stiff peaks gives the lightest texture, and folding gently keeps that air from collapsing.

Swap the orange

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

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

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