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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Beat the egg whites and yolks separately.
Cream the butter and sugar together until light.
Add the orange zest and juice, except for 1 tablespoon, to the butter mixture.
Mix in the cold water and part of the sifted flour with baking powder.
Add the egg yolks, then alternate with the remaining flour until combined.
Make the frosting
Beat the egg whites for the frosting in a separate bowl.
Add the reserved tablespoon of orange juice and 2 cups of sugar to the egg whites, and beat until light.
Bake and assemble
Pour the batter into two square cake tins and bake until golden.
Once slightly warm, layer frosting between the cakes and on top.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Eggs
- Whipped whites and yolks add lift and structure to the crumb.
- Butter
- Creaming with sugar traps air and adds tenderness and richness.
- Sugar
- Sweetens the cake and helps hold air when creamed and beaten.
- Flour
- Forms the structure that sets the cake as it bakes.
- Royal baking powder
- Releases gas in the batter so the cake rises and stays light.
- Orange
- Adds citrus aroma and a bright flavour from the zest and juice.
The step that matters
Folding in the egg yolks and flour. Adding flour in alternation with the batter keeps the mixture smooth and prevents overmixing, which would toughen the crumb and deflate the air beaten into the batter.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, butter, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
