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

What each ingredient does

Grated pineapple
Provides the main fruit flavor and the liquid that the filling is built on.
Flour
Thickens the filling as its starch swells and sets when boiled with the liquid.
Sugar
Adds sweetness and balances the tartness of the pineapple.
Butter
Adds richness and a smooth, silky mouthfeel when stirred into the hot filling.

The step that matters

Boil until it thickens. Flour thickens only when its starch granules swell and gelatinize at a full boil. If the mixture is not boiled long enough, the filling stays thin and can taste raw and floury.

Swap the pineapple

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

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Pineapplethe original

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