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

What each ingredient does

Stale cake
Provides a firm, absorbent base that holds the fruit between its layers.
Banana
Adds natural sweetness and a soft, creamy texture.
Pineapple
Adds acidity and juice that moistens the cake and brightens the flavour.
Sugar
Draws juice out of the fruit, sweetening it and softening the slices.
Whipped cream
Adds richness and moisture to the finished sandwiches.

The step that matters

Sprinkle the fruit with sugar and let it sit. Sugar draws juice out of the fruit. If the fruit is assembled too early or stays too wet, that liquid can soak the stale cake and make the sandwiches soggy.

Swap the pineapple

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

  1. Vanillafits better
  2. Strawberryfits better
  3. Pineapplethe original
  4. Figfits about as well

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