Why it works: Apple and pineapple match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 530 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Apple and Pineapple Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the pie
Preheat the oven to 350°F (175°C).
Line a deep pie plate with the pie crust.
In a bowl, mix chopped apples with ½ cup sugar, salt, and flour. Dot the apple mixture with bits of butter.
Bake until the apples are soft, about 30-40 minutes.
Make the pineapple layer
In a saucepan, simmer grated pineapple until tender. Add ¼ cup sugar and lemon juice to the pineapple, stirring well.
Spread the hot pineapple mixture over the baked apples.
Top with meringue and brown
Beat egg whites until soft peaks form. Gradually add powdered sugar.
Spread the meringue over the pineapple layer. Brown in the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the main fruit body, softening during baking to form the pie's filling.
- Egg whites
- Whipped into a foam that sets into a light, airy meringue topping.
- Sugar
- Sweetens the filling and the pineapple layer, and helps the meringue hold its structure.
- Flour
- Thickens the juices released by the apples so the filling holds together.
- Butter
- Adds richness and fat to the apple filling as it melts during baking.
- Pineapple
- Adds tangy, tropical flavour as a second fruit layer beneath the meringue.
The step that matters
Beat the egg whites to soft peaks before adding powdered sugar. Egg whites whipped to soft peaks trap air and form a stable foam; over-beating or adding sugar too early can make the meringue weep or stay flat, and it must be spread over the hot pineapple layer before browning.
