Why it works: Flour and milk 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
Make the filling
Extract the juice and grate the rind of the orange.
In a bowl, combine the orange juice, grated rind, sugar, and beaten egg yolks.
Blend the flour with a little cold milk, then add to the mixture along with the rest of the milk.
Bake and top
Pour the filling into the pastry crust and bake until set.
Make a meringue with the egg whites, sugar, and orange flavoring, then spread it over the pie.
Return the pie to the oven to brown the meringue.

Flour and milk 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 as it sets, and whites whip into the meringue topping.
- Flour
- Starch thickens the milk and juice mixture so the filling sets smoothly.
- Sugar
- Sweetens the filling and helps the meringue whip and hold its structure.
- Milk
- Adds creaminess and body to the custard-style filling.
- Orange
- Supplies juice for acidity and grated rind for citrus aroma.
The step that matters
Bake the filling until set. Egg and starch must be heated enough to thicken the filling, but overbaking can make it weep or curdle. Watch for the centre to firm without bubbling hard.
Swap the orange
How well each one fits the dish's main ingredients (flour, sugar, milk, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against flour, sugar, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
