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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Line a small pie dish with pastry.
Grate the yellow skin of the orange and cut the pulp into small pieces.
Combine the orange zest, pulp, and warm milk in a basin.
Beat the yolks of two eggs and whip the whites to a stiff froth.
Gently stir the egg yolks and whites into the orange mixture.
Bake
Sweeten to taste, pour into the lined pie dish, and bake at 350°F (175°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling and whipped whites lighten its texture as they set.
- Milk
- Provides moisture and body, forming the creamy base of the filling.
- Orange
- Supplies aroma and acidity, with zest adding fragrant oils and pulp adding juice.
- Sugar
- Adds sweetness to balance the acidity of the orange.
The step that matters
Folding in the whipped egg whites. Whites hold air only when whipped to a stiff froth; stirring them in gently keeps that air from collapsing, so the pie rises lightly and sets with a soft texture.
Swap the orange
How well each one fits the dish's main ingredients (milk, egg, sugar):
- Vanillafits better
- Figfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
