Pineapple Pie

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Grate the pineapples and sweeten them to taste.

Make the filling

  1. In a saucepan, melt the butter and stir in the flour until smooth.

  2. Add the grated pineapple to the butter mixture and combine well.

Bake and serve

  1. Pour the filling into the pie crust(s).

  2. Bake for 30-40 minutes or until the crust is golden.

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

What each ingredient does

Pineapples
Supplies the bulk of the filling, along with its juice, moisture and fruity flavour.
Sugar
Sweetens the tart pineapple and balances its acidity.
Butter
Adds richness and a rounded flavour to the filling.
Flour
Thickens the pineapple juice so the filling can set rather than run.
Pie crust
Holds the filling in shape and browns during baking.

The step that matters

Stir the flour into the butter until smooth before adding the pineapple. Flour lumps stay raw and chalky if not dispersed in fat first. Starch thickens the pineapple juice only when heated long enough, so the pie should bake until the crust is golden and the filling bubbles before it is cut.

Swap the pineapple

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

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

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