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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Add the juice and grated rind of the orange.
Mix and sift the flour and baking powder.
Add one unbeaten egg to the butter mixture and beat thoroughly.
Add a little flour, then the second egg, and beat well.
Alternate adding the remaining flour with the milk.
Mix thoroughly and bake in a 350°F (175°C) oven for about 30 minutes.
Finish
Frost with orange frosting.

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
- Butter
- Creamed with sugar to trap air, giving the cake a tender, rich crumb.
- Eggs
- Bind the batter and add structure as they set in the oven.
- Sugar
- Sweetens the cake and helps create a soft, tender texture when creamed with butter.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Milk
- Adds moisture and liquid so the flour hydrates into a smooth batter.
The step that matters
Adding the eggs one at a time and beating well. Eggs added too quickly to creamed butter can curdle the batter. Adding one egg at a time, with a little flour, keeps the emulsion stable so the cake bakes evenly and stays light.
Swap the orange
How well each one fits the dish's main ingredients (butter, egg, sugar, milk, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, egg, sugar, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
