Why it works: Peach and lemon work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 947 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Open Peach Pie
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Pare and halve the peaches.
Assemble
Line a pie plate with pastry and place the peaches cut side down.
Sprinkle ½ cup sugar over the peaches and add 1 teaspoon lemon juice.
Bake and serve
Bake until golden brown.
Serve cold with whipped cream or warm with cream and sugar.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Peaches
- Peaches form the filling, releasing juice that becomes a sweet, fragrant syrup as they bake.
- Sugar
- Sugar sweetens the filling and draws juice out of the fruit, thickening the syrup.
- Lemon juice
- Lemon juice adds acidity that brightens the peach flavor and balances the sugar.
- Pastry
- Pastry forms the base and sides, holding the filling while it bakes to golden brown.
The step that matters
Bake until golden brown. The juices thicken and the filling sets only when fully baked, so underbaking leaves a runny filling and soggy base. Overbaking dries the fruit and crust, so watch for even golden color rather than a fixed time.
Swap the lemon
How well each one fits the dish's main ingredients (peach, sugar):

- Apricotfits better
- Pearfits better
- Lemonthe original
Fit is the average pairing score against peach, sugar. Candidates are from the same food group and used in at least 100 recipes.
