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 Shortcake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix flour, baking powder, and salt.
Rub in the butter until smooth.
Add enough water or milk to form a soft dough.
Roll out the dough into two thin layers.
Spread butter between the layers to keep them separate.
Bake and assemble
Bake in the preheated oven until golden.
Split the layers.
Butter generously.
Fill with sliced bananas sprinkled with sugar.
Serve immediately with 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 dough as its proteins and starch set in the oven.
- Baking powder
- Releases gas during baking, lifting the dough so it becomes light and tender.
- Butter
- Adds fat that tenderises the dough and keeps the layers from fusing together.
- Water or milk
- Hydrates the flour so the dough holds together and becomes soft and pliable.
- Sugar
- Sweetens the bananas and draws out their juices for a syrupy filling.
- Sliced bananas
- Provide moisture and sweetness in the filling, softening as they sit against the warm layers.
The step that matters
Spread butter between the layers before baking. Fat coating the dough layers keeps them from fusing as they bake. This separation lets the layers rise and stay distinct, so the shortcake splits cleanly and has a tender, flaky texture.
Swap the banana
How well each one fits the dish's main ingredients (flour, butter, milk, sugar, cream):
- Vanillafits better
- Raisinfits better
- Coconutfits better
- Bananathe original
Fit is the average pairing score against flour, butter, milk, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
