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
Beat the yolks of the eggs with the powdered sugar until light.
Add the orange juice, grated orange zest, and cold water.
Gradually mix in the sifted flour and baking powder.
Fold in the stiffly beaten egg whites.
Bake and ice
Bake in layers at 350°F (175°C) until golden.
For icing, beat the egg whites until stiff, then add orange juice and zest, and enough sugar to stiffen.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Eggs
- Yolks enrich and bind the batter; whipped whites lighten the crumb and add rise.
- Powdered sugar
- Sweetens the batter and, beaten with the yolks, helps create a light, airy texture.
- All-purpose flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes lighter.
- Orange juice
- Adds moisture and bright citrus acidity and flavor to the cake and icing.
- Orange zest
- Contributes aromatic citrus oils that give the cake and icing their orange flavor.
The step that matters
Folding in the egg whites. Whipped whites hold the air that lightens the batter. Stirring them vigorously instead of folding gently knocks out that air, leaving a denser cake that rises less.
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.
