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 ↓
Banana Shortcake
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).
In a bowl, mix flour, sugar, eggs, butter, baking powder, and enough milk to create a thick batter.
Spread the batter on a baking sheet to a thickness of half an inch and bake until golden.
Assemble
Once cool, split the cake in half and layer sliced bananas in between.
Spread vanilla cream over the bananas, then place the top layer of cake on.
Add another layer of bananas and cream on top.
Top and serve
Beat the egg whites until stiff, then gradually add powdered sugar and spread over the top.
Brown the top in the oven and serve with additional cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the cake batter as it sets in the oven.
- Eggs
- Bind the batter and add structure and richness to the cake.
- Egg whites
- Whipped until stiff to form a light, glossy topping that holds its shape.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Butter
- Adds fat for tenderness and flavor in the cake.
- Bananas
- Add moisture and natural sweetness between the cake layers.
The step that matters
Beat the egg whites until stiff. Egg whites must be beaten until they hold stiff peaks before the powdered sugar is added gradually. Under-whipped whites will be runny and will not hold a topping shape, while over-whipped whites turn dry and grainy.
Swap the banana
How well each one fits the dish's main ingredients (flour, sugar, egg, butter, milk, vanilla, cream):

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