Why it works: Butter and milk 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
Grate the rind from the oranges and squeeze out the juice.
Beat the eggs and stir in the powdered sugar.
Add the melted butter, orange juice, and milk or cream to the egg mixture.
Bake
Pour the mixture into a puff pastry crust.
Bake at 350°F (175°C) until set, like a custard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the filling into a custard as they cook, giving it body.
- Powdered sugar
- Sweetens the filling and dissolves easily into the beaten eggs.
- Melted butter
- Adds richness and fat, giving a smooth, tender texture.
- Milk or cream
- Adds moisture and softness, making the custard silkier.
- Oranges
- Provide the citrus acidity and aroma from the juice and rind.
- Puff pastry
- Forms the crust that holds the filling while it bakes.
The step that matters
Bake until set, like a custard. Egg proteins set as they heat, so the pie is done when the centre wobbles slightly but no longer runs. Overbaking can make the custard grainy and weep liquid.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, butter, milk):
- Vanillafits better
- Figfits better
- Coconutfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
