Why it works: Pineapple and lemon are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 1,964 recipes. Both carry 2-nonenal, which smells fatty, 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
Preheat the oven to 350°F (175°C).
Line a pie plate with the crust.
Make the filling
In a bowl, combine the grated pineapple, melted butter, and powdered sugar.
Pour the mixture into the pie crust.
Bake and top
Bake until nearly done.
Meanwhile, make the meringue by beating the egg whites until stiff, then gradually add 3 tablespoons of powdered sugar and the lemon juice.
Spread the meringue over the pie and return it to the oven until the meringue is set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pineapple
- Provides the main fruit flavor, sweetness, and moisture for the filling.
- Egg whites
- Whipped into a foam that gives the meringue its structure and then sets in the oven.
- Powdered sugar
- Sweetens the filling and, added gradually, helps stabilize the meringue.
- Melted butter
- Adds fat and richness, giving the filling a smooth, tender texture.
- Lemon juice
- Adds acidity that brightens the pineapple flavor and helps steady the meringue.
The step that matters
Beating the meringue until stiff. Egg whites must be whipped until stiff, with sugar added gradually, to form a stable foam. Underbeaten whites stay runny and may slide off the pie, while overbeaten whites turn grainy and can weep or collapse as they bake.
Swap the pineapple
How well each one fits the dish's main ingredients (sugar, lemon, egg, butter):
