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 Cream Pie
Ingredients
Directions
Prepare the flavouring
Soak orange juice and grated peel together for 30 minutes, then squeeze through a muslin bag.
Make the filling
Stir the cornstarch into the boiling water.
Cream the butter and powdered sugar, then pour the hot cornstarch mixture over them.
Cool the mixture, then add the orange pulp and beaten egg.
Remove the inner rind and seeds from the half orange, chop finely, and add to the mixture.
Bake
Bake in pie shells until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Powdered sugar
- Sweetens the filling and dissolves smoothly into the creamed butter.
- Butter
- Adds richness and a smooth, creamy body to the filling.
- Egg
- Sets during baking to give the filling its structure.
- Cornstarch
- Thickens the boiling water into a starch paste that gives the filling body.
- Orange
- Provides the main citrus flavour and acidity from juice, peel and pulp.
The step that matters
Cool the mixture before adding the egg. Adding beaten egg to a very hot starch mixture can scramble it. Cooling first lets the egg blend smoothly, so it sets evenly into a silky filling when baked.
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.
