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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together until light and fluffy.
Beat in the egg yolks one at a time, mixing well after each addition for 15 minutes.
Gradually stir in the flour, then add the grated orange rind and juice.
Whisk the egg whites to stiff peaks and gently fold them into the mixture.
Prepare a baking tin lined with buttered paper and pour in the batter.
Bake and finish
Bake in a moderate oven at 350°F (175°C) for one hour.
Once cooled, ice the cake with orange icing and decorate the edge with crystallized orange sections.

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
- Castor sugar
- Sweetens the cake and helps trap air when creamed with butter, giving a lighter crumb.
- Butter
- Adds richness and a tender texture by coating flour and creaming with sugar.
- Flour
- Provides the structure that sets as the eggs and batter bake.
- Eggs
- Add richness and structure, and whipped whites add lift to the batter.
- Orange
- Adds bright aroma and acidity from the zest and juice.
The step that matters
Folding in the whipped egg whites. Whites whipped to stiff peaks hold air that makes the cake rise. Folding gently keeps that air in the batter, while vigorous stirring would deflate it and produce a denser cake.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter, flour, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
