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 ↓
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 oven to 350°F (175°C).
Cream butter and sugar together.
Add water and mix well.
In a separate bowl, combine flour and baking powder.
Gradually add dry ingredients to wet mixture.
Beat eggs and fold into batter.
Pour batter into prepared cake pans and bake until golden.
Make and spread the frosting
For frosting, mix egg yolk, pulverized sugar, and orange juice.
Beat egg whites to stiff peaks and fold into orange mixture.
Spread frosting between cake layers.

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
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- Flour
- Forms the cake's structure once it sets in the oven.
- Eggs
- Add structure and richness, and the whites whipped into the frosting lighten it.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Orange juice
- Adds acidity and bright citrus flavor to the frosting.
The step that matters
Fold the beaten egg whites into the orange mixture. Whipped egg whites hold air only while they are stiff and unbroken. Folding gently, rather than stirring, keeps the foam intact so the frosting stays light instead of deflating into a dense, runny layer.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, coffee):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, flour, egg, coffee. Candidates are from the same food group and used in at least 100 recipes.
