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 the filling
Preheat the oven to 350°F (175°C).
In a bowl, stir the egg yolks with sugar, a little grated orange peel, and butter.
Add the milk and the orange pulp and juice, mixing well.
Pour the mixture into a pie crust and bake until set.
Top and brown
Once cool, beat the egg whites with a little sugar and spread on top of the pie.
Return the pie to the oven and brown the meringue slightly.

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 as they set, giving the pie a rich, custard-like body.
- Orange pulp and juice
- Provide the main citrus flavour and acidity, along with liquid for the filling.
- Milk
- Adds moisture and softness, helping the filling set into a smooth custard.
- Egg whites
- Whip into a meringue that forms a light topping and browns in the oven.
- Sugar
- Sweetens the filling and helps the meringue whip and brown.
The step that matters
Bake the filling until set. Egg yolks thicken as their proteins coagulate with heat. Underbaking leaves a runny filling, while overbaking can make it weep or curdle, so the custard should be firm at the edges and only just set in the centre.
Swap the orange
How well each one fits the dish's main ingredients (sugar, milk, egg, butter):
- Vanillafits better
- Figfits better
- Coconutfits better
- Orangethe original
Fit is the average pairing score against sugar, milk, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
