Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Orange Cream 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 yolks of the eggs with the sugar until well combined.
Dissolve the flour and cornstarch in a little milk.
Add the dissolved mixture to the egg mixture.
Pour the mixture into the boiling water.
Cook the mixture until thick.
Let the filling cool.
Flavor the filling with orange extract.
Pour the filling into the baked crust.
Top and bake
Beat the egg whites until stiff.
Flavor the egg whites with orange.
Spread the egg whites over the pie.
Place the pie in a 350°F (175°C) oven to brown the meringue.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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.
- Sugar
- Sweetens the filling and helps stabilise the beaten egg whites.
- Flour
- Thickens the filling as it cooks.
- Cornstarch
- Adds thickening power so the filling sets smoothly when cooked.
The step that matters
Cook the filling until thick. Starch must be heated fully with the liquid to swell and thicken; undercooked filling stays runny and will not set properly when cooled.
Swap the orange
How well each one fits the dish's main ingredients (sugar, flour, egg):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
