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

What each ingredient does

Egg whites
Whipped to foam, they add lightness and help the filling set softly.
Sugar
Sweetens the filling and helps give it body as it dissolves into the mixture.
Orange juice
Adds acidity and fruity flavour that balances the sweetness.
Grated orange peel
Adds aromatic oils that give the filling a stronger orange flavour.

The step that matters

Beat the egg whites until frothy. Egg whites trap air when beaten, which gives the filling lightness. Under-beaten whites stay runny and dilute the filling, while over-beaten whites turn dry and grainy.

Swap the orange

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

  1. Vanillafits better
  2. Pineapplefits better
  3. Cherryfits better
  4. Orangethe original

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