Why it works: Orange and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 4,696 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓
Orange Pie
Ingredients
Directions
The book says “a quick 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).
Grate the peel of the oranges, avoiding the white part to prevent bitterness.
Make the filling
Beat the egg yolks with the sugar and grated orange peel.
Add the orange juice and milk to the mixture and stir well.
Pour the mixture into a pie dish.
Bake without an upper crust.
Make the topping and finish
Beat the egg whites until frothy.
Gradually add the powdered sugar to the egg whites.
Cover the pie with the frosting.
Lightly brown the frosting in the oven.

Sugar and milk barely smell alike, yet cooks put them together in 77,875 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
- Eggs
- Egg yolks set the filling into a custard, and whipped whites form the light topping.
- Orange
- Juice gives the filling its tart acidity, and the grated peel adds fragrant aroma.
- Sugar
- Sweetens the filling and balances the acidity of the orange.
- Milk
- Adds moisture and a creamy texture to the custard filling.
- Powdered sugar
- Sweetens the topping and gives it a smooth, fine texture.
The step that matters
Lightly browning the frosting. Sugar darkens quickly under heat, so the frosting can turn bitter or burn in a short time. Watch it closely and remove the pie once it is lightly golden.
Swap the orange
How well each one fits the dish's main ingredients (sugar, egg, milk):
- Vanillafits better
- Figfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
