Why it works: Apple and cinnamon are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 5,598 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓
Apple Pie
Ingredients
Directions
The book gives no oven temperature. The 425°F (220°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the dough
In a bowl, mix flour, salt, and sugar.
Cut in butter until mixture resembles coarse crumbs.
Stir in ice water, a tablespoon at a time, until dough forms a ball.
Divide dough in half, shape into discs, wrap in plastic, and refrigerate for 4 hours or overnight.
Assemble the pie
Preheat oven to 425°F (220°C).
Roll out one disc of dough on a floured surface to fit a 9-inch pie plate.
Place the rolled dough in the pie plate and fill with sliced apples.
In a bowl, mix sugar, flour, and cinnamon; sprinkle over apples.
Dot with butter and cover with the second rolled disc of dough.
Seal edges and cut slits in the top crust for steam to escape.
Bake
Brush with beaten egg and bake for 15 minutes.
Reduce temperature to 350°F (175°C) and bake for 30 to 35 minutes until apples are soft.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- All-purpose flour
- Provides the structure that holds the dough together and sets around the filling.
- Unsalted butter
- Stays in cold pieces in the dough, creating flaky layers as it melts and steams during baking.
- Apples
- Form the filling, softening as they bake and releasing juices that thicken with the flour.
- Sugar
- Adds sweetness and helps the filling juices become syrupy as the apples cook.
- Egg
- Brushed on the top crust to promote browning and a glossy finish.
The step that matters
Keep the butter cold when cutting it into the flour. Small cold butter pieces melt during baking and leave pockets that make the crust flaky. If the butter softens or melts into the flour, the crust becomes dense and tough.
Swap the apple
How well each one fits the dish's main ingredients (flour, sugar, butter, cinnamon, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Applethe original
Fit is the average pairing score against flour, sugar, butter, cinnamon, egg. Candidates are from the same food group and used in at least 100 recipes.
