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
Make the syrup
Boil the apple cores with water until flavorful, then strain.
Add sugar and cinnamon to the strained liquid and simmer.
Assemble and bake
Place the pie crust in a dish and fill with a layer of apples.
Sprinkle half the sugar, lemon zest, and lemon juice (or cider) over the apples.
Add the remaining apples, sugar, and the boiled liquid.
Cover with the pie crust and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Make up the filling, softening as they bake to form the body of the pie.
- Sugar
- Adds sweetness and helps the apples and liquid caramelize and brown in the oven.
- Lemon
- Its juice adds acidity that brightens the apple flavor, and its zest adds aroma.
- Cinnamon
- Adds warm, aromatic spice to the cooking liquid that flavors the apples.
- Pie crust
- Holds the filling in place and browns to a golden finish in the oven.
