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 Cake
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 cake
Preheat the oven to 350°F (175°C).
In a bowl, mix the egg yolks, sugar, flour, grated orange rind, and baking powder until well combined.
Divide the batter into layers and bake until golden.
Make the filling and assemble
For the filling, beat the egg whites until stiff peaks form.
Gradually add the sugar and orange juice, mixing until smooth.
Spread the filling between the layers of cake.

Egg and flour 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
- Egg yolks
- Add richness and structure to the batter as they set during baking.
- Flour
- Provides the structure that holds the cake's layers together.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Egg whites
- Whipped to stiff peaks, they trap air and give the filling a light, airy texture.
- Sugar
- Sweetens the cake and helps the batter brown as it bakes.
The step that matters
Beating the egg whites to stiff peaks. Whites that are under-whipped or greasy won't hold air, so the filling turns runny and loses its lightness. Whites should be clean and free of yolk before whipping.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
