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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the egg whites and mix well.
Stir in the milk and flour until combined.
Make the filling
For the filling, cook the stewed apple, grated oranges, and beaten egg yolks with sugar until thick like cream.
Combine and bake
Pour the filling into the cake batter and mix gently.
Pour the batter into a greased cake pan and bake for 30-35 minutes.
Frost
For the frosting, beat the egg yolk and spread it on top of the cake after it cools.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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.

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
- Eggs
- Egg whites add structure and lift, while yolks add richness and help set the filling.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Adds sweetness and helps keep the crumb tender.
- Milk
- Adds moisture to the batter.
- Oranges
- Add citrus aroma and acidity to the filling.
The step that matters
Cooking the filling until thick like cream. Heat sets the egg yolks, which thickens the filling. Too little heat leaves it runny, and too much can scramble the yolks.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, flour, apple):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, butter, egg, milk, flour, apple. 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.
