Why it works: Apple and peach match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 303 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Rhubarb, Peach, or Apple 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.
Prepare
Preheat the oven to 400°F (200°C).
Peel the fruit and slice it.
Prepare the under crust in the saucers.
Fill and bake
Fill deep saucers with the fruit.
Sprinkle the fruit with sugar, dredge it with flour, and dust it with nutmeg or cinnamon.
Cut rhubarb into 1-inch pieces and mix it with 1 cup of sugar and 1 tablespoon of flour.
Place the rhubarb mixture in the saucers.
Cover with the upper crust.
Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fruit (in the method)
- Provides the main filling, along with its natural sweetness and tartness.
- Sugar
- Sweetens the filling and draws out juices that help form a syrup.
- Flour
- Thickens the juices so the filling sets rather than running out.
- Pie crust
- Forms the structure that holds the filling and browns in the oven.
The step that matters
Thickening the filling with flour. Flour must be evenly mixed with the sugar and fruit so the juices thicken as they heat. Unevenly distributed flour can leave pockets of runny filling or raw starch taste.
Swap the apple
How well each one fits the dish's main ingredients (rhubarb, sugar, peach, flour, nutmeg):
- Vanillafits better
- Raisinfits better
- Blueberryfits better
- Applethe original
Fit is the average pairing score against rhubarb, sugar, peach, flour, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
