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 ↓
Okange 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 the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the milk and mix well.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture.
Finish and bake
Beat the egg yolks and fold them into the batter.
In another bowl, beat the egg whites until stiff peaks form, then gently fold them into the batter.
Stir in the juice of 1 orange.
Pour the batter into jelly cake tins and bake until golden.
Make the icing
For the icing, beat the egg whites until stiff, then gradually add sugar until thick.
Mix in the juice and grated rind of 2 oranges and spread between the layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift, while yolks add richness and help bind the batter.
- All-purpose flour
- Forms the structure that holds the cake's shape as it bakes.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Sugar
- Sweetens the cake and helps create a soft, tender texture when creamed.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Milk
- Adds moisture and helps the batter come together smoothly.
The step that matters
Fold the beaten egg whites gently into the batter. Whites hold air that gives the cake its lift. Vigorous stirring deflates them, leaving a dense, heavy crumb.
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.
