Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pineapple Raisin 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.
Make the filling
Combine pineapple, raisins, and water in a saucepan and boil for 3 minutes.
Remove from heat and stir in sugar, salt, and flour until blended.
Let the mixture cool until half set.
Add the beaten egg and butter to the mixture and stir well.
Assemble and bake
Pour the filling into a prepared pie shell and cover with a top crust.
Bake at 400°F (200°C) for about 25 minutes, until the pie is well browned.
Optionally, add a teaspoon of lemon juice or vinegar to the filling.

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
- Raisins
- Add chewy texture and concentrated sweetness to the filling.
- Pineapple
- Provides fruity moisture and flavour that forms the body of the filling.
- Egg
- Helps the beaten filling thicken and set as it cools and bakes.
- Flour
- Thickens the filling so it holds its shape when cut.
- Sugar
- Adds sweetness and helps balance the tartness of the fruit.
- Butter
- Adds richness and fat for a smoother, more tender filling.
The step that matters
Cooling until half set. Letting the mixture cool before adding the egg keeps the egg from scrambling and lets the starch-thickened filling reach a body that holds during baking.
Swap the pineapple
How well each one fits the dish's main ingredients (raisin, flour, egg, sugar, butter):

Fit is the average pairing score against raisin, flour, egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
