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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the egg yolks and whole egg, mixing well.
Stir in the cold water, flour, baking powder, and orange juice until combined.
Divide the batter into two greased cake pans.
Bake and finish
Bake for 25-30 minutes or until a toothpick comes out clean.
Let the cakes cool before frosting with boiled icing and adding grated orange rind.

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
- Adds fat and richness, contributing tenderness and flavour to the crumb.
- Egg yolks
- Add richness and emulsify the batter, helping give a tender, moist crumb.
- Flour
- Provides the structure that sets the cake's crumb as it bakes.
- Baking powder
- Releases gas during baking, making the cake rise and become light.
- Sugar
- Sweetens the cake and helps create a tender, browned crust.
- Orange juice
- Adds moisture and bright acidity that flavours the cake.
The step that matters
Testing for doneness. Baking for the full 25-30 minutes can overbake the cake, drying the crumb. Checking with a toothpick near the start of the range helps the cake stay moist, since the centre sets as the starches gelatinise and the proteins coagulate.
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.
