Why it works: Flour and butter 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 oven to 350°F (175°C).
Beat butter and sugar together until creamy.
Add beaten egg yolks, then mix in flour, baking powder, and cold water.
Fold in beaten egg whites gently.
Stir in grated orange rind and orange juice, reserving 1 tablespoon.
Bake and frost
Pour batter into prepared cake pans and bake until golden.
Beat 2 egg whites until stiff; gradually add 6 tablespoons sugar and 1 tablespoon orange juice.
Spread frosting between layers and on top of cake.

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.

Flour and butter 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
- Egg yolks enrich the batter, while whipped whites add lift and a light, airy crumb.
- Butter
- Creams with sugar to trap air and adds fat for a tender, moist crumb.
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Sweetens the cake, helps it brown, and stabilises the whipped egg white frosting.
The step that matters
Folding in the beaten egg whites. Stirring vigorously knocks out the air trapped in the whites, which deflates the batter and produces a dense cake. Gentle folding keeps the air bubbles that give the cake its rise.
Swap the orange
How well each one fits the dish's main ingredients (sugar, flour, butter, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
