Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Orange Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
Beat the egg yolks and sugar together.
Add the flour, milk, and grated rind and juice of the orange.
Cook in a double boiler, stirring until slightly thickened.
Bake and top
Pour the mixture into a pie crust brushed with egg white.
Bake for 30 minutes at 350°F (175°C).
Top with meringue made from the egg whites sweetened with 3 tablespoons of sugar.
Brown the meringue in the oven for a moment.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Yolks thicken the filling and whites form the meringue topping, giving structure.
- Sugar
- Sweetens the filling and the meringue, and helps the meringue hold its shape.
- Flour
- Helps thicken the filling so it sets into a sliceable custard.
- Milk
- Adds moisture and richness, forming the body of the custard filling.
- Orange
- Supplies juice and rind for citrus flavour and acidity that cuts the sweetness.
The step that matters
Cook the filling until slightly thickened. Egg yolks thicken as they heat, but overheating can curdle them. Gentle stirring in a double boiler keeps the custard smooth while it sets.
Swap the orange
How well each one fits the dish's main ingredients (milk, egg, sugar, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against milk, egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
