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 ↓
Banana 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).
In a bowl, cream together the sugar and butter.
Add the eggs and mix well.
Stir in the sweet milk and banana extract.
In another bowl, combine the flour and baking powder, then gradually add to the wet mixture.
Divide the batter into two greased cake pans.
Bake and assemble
Bake for 25-30 minutes or until a toothpick comes out clean.
Once cooled, layer the cakes with thinly sliced bananas, lemon juice, powdered sugar, and whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Creams with the sugar to add fat, tenderness and a rich texture.
- Flour
- Forms the main structure of the cake crumb as it bakes.
- Baking powder
- Releases gas in the batter so the cakes rise and turn light.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
- Bananas
- Add fruit flavour and moisture between the cake layers.
The step that matters
Dividing and baking the batter. Batter should be spread evenly between the pans so both layers bake at the same rate. Baking powder starts working once wet and dry mixtures combine, so the batter should go into the oven promptly. Checking with a toothpick confirms the centre is set and not wet.
Swap the lemon

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