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
Prepare the batter
Beat the egg whites and yolks separately.
Cream together the sugar and butter.
Add the cold water, flour, baking powder, grated orange rind, and all but 1 tablespoon of the orange juice to the mixture.
Bake and frost
Bake in layers.
For the frosting, beat the egg whites and gradually add the sugar and orange juice.
Once the cake is cold, layer it with frosting and frost the 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
- Egg whites
- Whipped separately to add air and lift to the cake crumb.
- Egg yolks
- Add richness and fat, helping the cake turn tender and moist.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Butter
- Adds fat for tenderness and flavour when creamed with the sugar.
- Sugar
- Sweetens the cake and helps create a soft, fine crumb when creamed.
The step that matters
Add the orange juice carefully. Keep back 1 tablespoon of juice as the record directs. Too much liquid thins the batter and can weaken its rise, while the baking powder needs a steady, well-mixed batter to lift the cake evenly.
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.
