Why it works: Milk and butter 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.
Make the cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together gradually.
Beat in the egg yolks.
Add the sifted flour mixed with baking powder alternately with the milk.
Fold in the stiffly beaten egg whites.
Divide the batter into two cake pans and bake until golden.
Make the banana filling
For the banana filling, press the banana pulp through a sieve to fill a cup.
Mix in the sugar, lemon juice, lemon rind, and unbeaten egg white.
Beat until the mixture is solid to the bottom of the bowl, about 20 minutes.
Use the banana filling between the two cakes and on top.
Decorate and serve
Mix confectioner's sugar with lemon juice and water to a smooth paste for the topping.
Decorate with candied cherries.

Flour and butter 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
- Creams with sugar to give the cake a tender, rich crumb.
- Eggs
- Egg yolks enrich the batter and stiffly beaten whites lighten it for structure.
- Flour
- Forms the main structure of the cake as the batter sets in the oven.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Banana pulp
- Adds moisture and banana flavour to the filling between and on top of the cakes.
- Milk
- Adds moisture and softens the batter as it is combined with the flour.
The step that matters
Beating the banana filling until solid. The filling must be beaten long enough to thicken and hold its shape between the cakes. Under-beating leaves it runny, so it soaks into the sponge instead of staying as a layer.
Swap the banana
How well each one fits the dish's main ingredients (milk, sugar, flour, egg, butter, lemon):
- Vanillafits better
- Raisinfits better
- Figfits better
- Bananathe original
Fit is the average pairing score against milk, sugar, flour, egg, butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
