Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Orange Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
Beat the sugar and butter together until creamy.
Add the beaten egg yolks, orange juice, orange rind, nutmeg, and cornstarch; mix well.
Fold in the beaten egg whites until combined.
Place the mixture in a saucepan over hot water and stir until thick and smooth.
Bake
Line a pie plate with pastry, pour in the filling, and bake at 400°F (200°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the filling and helps cream with the butter to give a light base.
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a softer texture.
- Eggs
- Provide structure as the filling sets, and the whites add lightness when folded in.
- Cornstarch
- Thickens the filling as it heats, giving a smooth, sliceable set.
- Orange
- Supplies acidity and citrus aroma from the juice and grated rind.
The step that matters
Thickening over hot water. Cornstarch thickens only as the mixture heats, and gentle heat over hot water lets it set smooth. Too much heat can scramble the eggs, so stir steadily and keep the water below a hard boil.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter, egg):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
