Why it works: Vanilla and banana are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,430 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓

Ingredients
Directions
Prepare
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the well-beaten egg yolks and mix well.
Sift the flour, baking powder, and salt together five times.
Make the batter
Add 1 cup of the sifted flour to the mixture, then add the remaining flour and the milk.
Fold in the mashed bananas and the stiffly beaten egg whites.
Bake
Pour the batter into prepared cake pans and bake for 25 to 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and whites, beaten stiff and folded in, lighten the crumb.
- All-purpose flour
- Gluten forms the structure that holds the cake's crumb together as it bakes.
- Butter
- Creamed with sugar, it traps air and adds tenderness and richness to the crumb.
- Sugar
- Creamed with butter, it adds sweetness and helps the cake brown.
- Baking powder
- Releases gas in the batter, causing the cake to rise.
- Mashed bananas
- Add moisture, sweetness and banana flavor to the crumb.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold air that gives the cake its lift. Overmixing or stirring vigorously deflates them, leaving a dense cake, so fold gently until just combined.
Swap the banana
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, vanilla, flour):

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