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.
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the milk and flour, mixing until smooth.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the batter.
Bake
Pour the batter into prepared cake pans and bake at 350°F (175°C) until golden.
Make the filling and assemble
For the filling, beat the egg white with powdered sugar and the juice and grated rind of the orange until thick enough to spread.
Spread the orange filling between the layers of cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that makes the cake tender and rich in flavour.
- Sugar
- Sweetens the cake, helps it brown, and softens its crumb.
- Eggs
- Whipped whites add lift and structure; yolks add richness and set the crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Milk
- Adds moisture so the batter mixes smoothly and the cake stays soft.
- Orange
- Its juice adds acidity and its grated rind adds bright aroma to the filling.
The step that matters
Folding in the egg whites. Whipped whites hold air that makes the cake rise. Stirring hard or briskly knocks that air out, leaving a dense cake, so fold gently until just combined.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, milk, flour, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
