Why it works: Apple and cider are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 1,238 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓
Apple Pie
Ingredients
Directions
Prepare the filling
Pare and core the apples, wiping the outside clean.
Boil the apple peels and cores with a little water until flavorful; strain.
Add sugar and bruised cinnamon to the strained liquid and simmer again.
Assemble and bake
Place a layer of apples in a dish and add a pastry edge.
Sprinkle half the sugar, lemon peel, and a splash of cider if needed over the apples.
Add the remaining apples, sugar, and the boiled liquid on top.
Cover with pastry and bake until golden brown.
Serve
Serve hot with butter or flavor with marmalade, orange paste, or cloves if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Form the bulk of the filling, cooking down to soft, tender slices.
- Sugar
- Adds sweetness and helps the apples release juices that form the syrup.
- Pastry
- Encloses the filling and browns in the oven to form the crust.
- Apple peels and cores
- Boiled into a liquid that adds concentrated apple flavor to the filling.
- Bruised cinnamon
- Adds warm aromatic flavor to the simmered liquid.
The step that matters
Bake until golden brown. Baking long enough sets the juices into a thickened filling and fully browns the pastry; underbaking leaves a runny filling and pale, soggy crust.
Swap the lemon
How well each one fits the dish's main ingredients (apple, sugar, cinnamon, cider, butter):

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