Why it works: Flour and sugar 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.
Prepare and bake
Preheat the oven to 350°F (175°C).
Mix flour, sugar, water, baking powder, egg yolks, and egg whites until smooth.
Pour the batter into a cake pan.
Bake until a toothpick comes out clean.
Make the filling and assemble
Beat the egg whites.
Mix in the grated orange rind and juice.
Add sugar to thicken the mixture.
Spread the dressing between the baked cake layers.
Return to the oven for 1 minute.

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
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Eggs
- Egg whites trap air for lift, and yolks add richness and help set the crumb.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Sweetens the cake and, when added to the egg whites, helps thicken the dressing.
- Orange juice
- Adds acidity and bright citrus flavour to the dressing.
The step that matters
Beat the egg whites. Egg whites must be beaten to hold air bubbles; under-beaten or greasy whites will not trap air well, so the dressing and cake lose volume and lightness.
Swap the orange
How well each one fits the dish's main ingredients (flour, sugar, egg):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
