Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the sugar and butter together until light and fluffy.
Whip the egg whites to stiff peaks.
Gently fold the whipped egg whites into the creamed mixture.
Gradually stir in the sifted flour.
Add the orange flavor.
Bake
Pour the batter into square pans.
Bake immediately in a 400°F (200°C) oven until golden.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Sugar
- Sweetens the cake and helps the creamed butter hold air for a light texture.
- Butter
- Adds fat for tenderness and rich flavor, and traps air when creamed with sugar.
- Egg whites
- Whipped to stiff peaks, they trap air that lifts and structures the cake.
- Flour
- Provides the structure that holds the cake's shape once it sets.
The step that matters
Fold the whipped egg whites gently. Whipped whites hold air bubbles that make the cake rise. Stirring hard or overmixing deflates them, which leaves a denser, flatter cake.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter, egg, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
