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 batter
Preheat the oven to 350°F (175°C).
Beat the yolks of 5 eggs with 2 cups of sugar until well combined.
Add ½ cup of cold water, juice, and rind of 1 orange, and mix well.
Sift in 2 cups of flour and 2 teaspoons of baking powder, and stir until smooth.
In a separate bowl, beat the whites of 4 eggs until stiff peaks form.
Gently fold the beaten egg whites into the batter.
Bake and fill
Pour the batter into square pans and bake until golden.
For the filling, beat 1 egg white, then add juice and rind of 1 orange, and confectionery sugar until stiff.
Spread the filling between the layers of the 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 help bind the batter for a tender crumb.
- Sugar
- Sweetens the cake and helps keep it moist and tender.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Egg whites
- Whipped to stiff peaks, they trap air that lightens the batter.
- Orange juice and rind
- Adds citrus acidity and aroma that flavour the cake.
The step that matters
Folding in the beaten egg whites. Stirring vigorously knocks out the air whipped into the whites, so the cake rises less and turns dense. Fold gently, using a large spatula and a sweeping motion, to keep the batter light.
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.
