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
Make the custard
Cream together powdered sugar and butter.
Mix cornstarch with a little cold water, then add boiling water to the cornstarch mixture.
Cook until thickened, stirring constantly.
Pour the thickened mixture into the creamed butter and sugar.
Grate peel from one orange. Chop the other half of orange, removing inner white skin.
Add grated peel and chopped orange to the mixture along with beaten egg and orange juice.
Prepare the crust and filling
Peel and slice another orange into thin bits, removing all seeds and tough white skin.
Line a pie plate with pie crust and bake until just done.
Fill crust with custard mixture and orange slices.
Bake until egg is cooked.
Top and finish
Beat egg whites with a pinch of salt and 2 tablespoons powdered sugar until stiff.
Spread meringue over pie.
Sift powdered sugar on top.
Return to oven until slightly colored.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolk and whites set the custard and give the meringue its structure.
- Cornstarch
- Thickens the boiling water into a smooth custard that holds the orange pieces.
- Butter
- Adds richness and a tender texture to the creamed base.
- Powdered sugar
- Sweetens the custard and the meringue, and helps the meringue stay glossy.
- Orange
- Provides juice, zest and slices for bright citrus flavor and aroma.
The step that matters
Cook the cornstarch mixture until thickened, stirring constantly. Cornstarch only thickens fully when it reaches a boil and is stirred, so the gelatinized starch sets the custard evenly. Stopping early leaves a thin filling, and letting it sit without stirring can scorch or clump it.
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.
