Why it works: Butter and pineapple are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 1,134 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. 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.
Make the filling
Preheat the oven to 350°F (175°C).
Beat the butter and powdered sugar until creamy.
Add the beaten yolks of the eggs and the shredded pineapple; mix well.
Gently fold in the beaten egg whites until just combined.
Bake
Pour the mixture into a pie plate with an under-crust only.
Bake until set and lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a tender texture.
- Powdered sugar
- Adds sweetness and dissolves smoothly into the creamed butter.
- Eggs
- Yolks enrich and thicken the filling, while the whites set it as it bakes.
- Pineapple
- Adds moisture and bright, slightly tart fruit flavor to the filling.
The step that matters
Fold in the egg whites gently. Beaten egg whites hold air that gives lightness. Stirring them vigorously deflates the foam, leaving a denser, less airy pie once it sets in the oven.
Swap the pineapple
How well each one fits the dish's main ingredients (sugar, butter, egg):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Pineapplethe original
Fit is the average pairing score against sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
