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
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, combine the flour and baking powder.
Gradually add the flour mixture to the butter mixture, alternating with the milk.
Bake and frost
Pour the batter into jelly‑cake tins and bake until golden.
For the frosting, beat the reserved egg whites until stiff.
Add the orange juice and grated peel, then mix in sugar until the frosting reaches the desired consistency.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cake a tender, rich crumb.
- Eggs
- Add structure and richness, and their whites whip into the frosting.
- All-purpose flour
- Forms the main structure of the cake as it sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps create a light, fluffy creamed base.
- Milk
- Adds moisture to the batter, keeping the crumb soft.
The step that matters
Adding the eggs one at a time. Each egg must be fully incorporated before the next is added; otherwise the batter can curdle or separate, and the cake may turn out dense.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, flour, milk, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, flour, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
