Why it works: Apple and lemon are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Apple Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Line a deep pie plate with pie crust.
Assemble and bake
Layer sliced apples in the crust, sprinkling with brown sugar, mace or cinnamon, lemon peel, and butter.
Add another layer of apples and seasoning.
Cover with a top crust and bake until golden.
After baking, leave the pie in the oven with the door open for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the bulk and fruity body of the filling as they soften while baking.
- Brown sugar
- Adds sweetness and helps caramelise the juices into a rich syrup.
- Butter
- Adds fat for richness and a smoother mouthfeel in the filling.
- Pie crust
- Forms the structural case that holds the filling and browns in the oven.
The step that matters
Leaving the pie in the oven with the door open. Cooling slowly with the door ajar lets the filling thicken gradually and reduces the risk of a soggy crust. Following the record's timing matters here.
Swap the mace
How well each one fits the dish's main ingredients (apple, sugar, lemon, butter):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits better
- Macethe original
Fit is the average pairing score against apple, sugar, lemon, butter. Candidates are from the same food group and used in at least 100 recipes.
