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 ↓
Hot 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).
Place a layer of apples in a pie dish.
Sprinkle half the sugar and lemon peel over the apples.
Squeeze lemon juice or add cider if the apples are not tart.
Assemble
Add the remaining apples, sugar, and any liquid from boiling.
Cover with pie crust.
Bake and serve
Bake until golden brown.
Add butter when serving 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, softening and releasing juices as they bake.
- Sugar
- Adds sweetness and helps draw moisture out of the apples to form a syrup.
- Lemon peel
- Adds bright aroma from its fragrant oils.
- Lemon juice
- Adds acidity that balances the sugar and keeps the apple flavor lively.
- Butter
- Adds fat and richness to the warm filling when served.
The step that matters
Adjust the tartness before covering the pie. Apples vary in acidity, and sugar alone can make a filling taste flat or cloying. Lemon juice or cider adds acid that balances sweetness, so tasting the apples first and adding liquid only if they are not tart helps the filling taste balanced.
Swap the lemon
How well each one fits the dish's main ingredients (apple, sugar, cider, butter):
- Pearfits better
- Plumfits better
- Peachfits better
- Lemonthe original
Fit is the average pairing score against apple, sugar, cider, butter. Candidates are from the same food group and used in at least 100 recipes.
