Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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
Preheat the oven to 350°F (175°C).
Make the filling
In a bowl, mix the orange juice, grated rind, sugar, egg yolks, cornstarch, butter, and milk until smooth.
Pour the mixture into a pie crust and bake until set.
Top and brown
Whip the egg whites with sugar until stiff peaks form.
Spread the whipped egg whites on top of the baked pie and return to the oven until browned.

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 add richness and a custard-like set.
- Cornstarch
- Thickens the orange filling so it sets firm when baked.
- Egg whites
- Whipped into a foam that forms the browned meringue topping.
- Sugar
- Sweetens the filling and helps stabilise the whipped egg whites.
- Orange juice and rind
- Provide the citrus acidity and aroma that flavour the filling.
The step that matters
Whipping the egg whites to stiff peaks. Egg whites need to be whipped until they hold stiff peaks so the meringue keeps its volume and browns evenly. Under-whipped whites will weep or collapse, and any trace of fat or yolk in the bowl prevents them from foaming properly.
Swap the orange
How well each one fits the dish's main ingredients (sugar, egg, milk, butter, chestnut):
- Vanillafits better
- Figfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against sugar, egg, milk, butter, chestnut. Candidates are from the same food group and used in at least 100 recipes.
