Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Plain Pineapple Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Line a shallow 9 or 10 inch pie pan with flake pastry.
In a bowl, mix the pineapple with sugar, flour, and salt.
Place 1 tablespoon of flour in the bottom of the lined pie pan and rub it into the pastry to close the pores.
Assemble and bake
Pour the pineapple mixture into the pan and dot with butter at regular intervals.
Make an upper crust using your preferred method.
Bake for about 25 minutes or until well browned.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Diced canned pineapple
- Provides the fruit filling and most of the moisture that the pastry must contain.
- Sugar
- Adds sweetness and helps thicken the juices as the filling cooks.
- Flour
- Thickens the pineapple juices so the filling sets rather than running out of the crust.
- Butter
- Adds richness and flavor to the filling as it melts into the fruit.
The step that matters
Rubbing flour into the bottom crust. A thin layer of flour on the pastry absorbs juice from the fruit, helping keep the bottom crust from becoming soggy during baking.
Swap the pineapple
How well each one fits the dish's main ingredients (sugar, flour, butter):

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