Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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).
Cream the butter and sugar together.
Separate the eggs; beat the yolks until creamy and add to the butter and sugar mixture.
Beat well, then stir in the milk and flour alternately, adding the baking powder sifted with the flour.
Fold in the beaten egg whites and the orange juice.
Bake and fill
Bake in four layers.
For the filling, grate the rind of 2 oranges and mix with the juice and powdered sugar; spread between the layers.
Ice the cake as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb.
- Egg yolks
- Add richness and emulsify the batter, helping it hold together.
- Egg whites
- Beaten and folded in, they trap air that helps the cake rise and stay light.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking powder
- Releases gas during baking, making the cake rise.
- Sugar
- Sweetens the cake and helps tenderise its texture.
The step that matters
Folding in the egg whites. Beaten whites hold trapped air that lifts the batter. Overmixing or deflating them while folding makes the cake dense and flat.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter, flour, milk, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, butter, flour, milk, 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.
