Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Orange Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Preheat the oven to 350°F (175°C).
In a bowl, combine the grated lemon and orange rinds with their juices.
In another bowl, beat together the sugar, egg yolks, and butter until creamy.
Pour the mixture into a pie crust and bake until set.
Make the meringue and finish
In a separate bowl, beat the egg whites with powdered sugar until stiff peaks form.
Once the pie is done, cover it with the meringue and return to the oven to stiffen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the filling and enrich it, helping it set as it bakes.
- Egg whites
- Whipped into a foam that forms the light, stable meringue topping.
- Sugar
- Sweetens the filling and helps stabilise the egg yolk mixture.
- Butter
- Adds fat for a rich, smooth texture in the filling.
- Orange
- Provides citrus aroma and acidity through its rind and juice.
The step that matters
Beat the egg whites to stiff peaks. Egg whites need to be whipped until they hold firm peaks so the meringue stays airy and stands up during the second baking. Underbeaten or greasy whites will weep or collapse.
Swap the orange
How well each one fits the dish's main ingredients (lemon, sugar, egg, butter):
- Vanillafits about as well
- Orangethe original
- Raspberryfits about as well
- Figfits about as well
Fit is the average pairing score against lemon, sugar, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
