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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the egg whites and mix well.
Stir in the sweet milk and orange flavoring.
In a separate bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, mixing until smooth.
Bake and finish
Pour the batter into a greased cake pan and bake for 25-30 minutes.
For the icing, boil orange juice and sugar until thick, then cool slightly.
Spread icing between the layers and on top of the cake while still soft.
Decorate the top with oranges cut into eighths.

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
- Creaming with sugar traps air and gives the cake a tender, rich crumb.
- Egg whites
- Provide structure and help the cake set and hold its rise as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the acid in the cream of tartar to produce gas that lifts the batter.
- Cream of tartar
- Acts as an acid that works with the baking soda to help the cake rise and stay light.
- Sugar
- Sweetens the cake, helps create a tender crumb, and dissolves into the icing to thicken it.
The step that matters
Gradually adding the dry ingredients. Adding flour in portions and mixing only until smooth keeps the batter from overdeveloping gluten, which would make the cake tough. Blending too vigorously can also knock out the air and gas the leavening needs to rise.
Swap the orange
How well each one fits the dish's main ingredients (butter, milk, sugar, egg, cream, flour):
- Vanillafits better

- Coconutfits better
- Orangethe original
Fit is the average pairing score against butter, milk, sugar, egg, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
