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 ↓
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.
Prepare the filling
Chop the pineapple finely and drain it, measuring the juice.
In a bowl, combine the chopped pineapple, sugar, beaten eggs, flour, and salt.
Pour in 1 cup of the pineapple juice, adding water if necessary to make a full cup.
Add lemon juice to taste.
Dot the mixture with small pieces of butter.
Assemble and bake
Pour the mixture into a pie crust.
Top the crust with strips of pastry.
Bake at 350°F (175°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the filling and help it set as it bakes.
- Flour
- Thickens the juice so the filling holds its shape when cut.
- Sugar
- Sweetens the filling and balances the tartness of the pineapple.
- Pineapple
- Provides the main fruit flavor and moisture for the filling.
- Butter
- Adds richness and flavor to the filling.
The step that matters
Pour in 1 cup of the pineapple juice, adding water if necessary to make a full cup.. The liquid must be measured accurately, because too little thins the set of the eggs and flour and too much leaves the filling runny after baking.
Swap the pineapple
How well each one fits the dish's main ingredients (sugar, lemon, flour, butter, egg):

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