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 Loaf 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.
Prepare
Preheat the oven to 350°F (175°C).
In a large bowl, cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Sift together the flour and baking powder, then gradually add to the mixture.
Stir in the orange juice and grated orange rind until well combined.
Bake
Pour the batter into a greased loaf pan and bake for about 50-60 minutes, or until a toothpick inserted in the center comes out clean.
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.

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, giving the cake a light, tender crumb and rich flavor.
- Sugar
- Sweetens the cake and creaming with butter helps create a fine, airy structure.
- Eggs
- Add structure as they set in the oven and help bind the batter together.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the loaf rises and becomes light.
- Orange juice
- Adds moisture and bright citrus acidity to the batter.
The step that matters
Adding the eggs one at a time. Adding eggs gradually and mixing well after each lets the emulsion form smoothly. Adding them all at once can cause the batter to curdle or separate, which affects the final texture.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, flour, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
