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 Shortcake
Ingredients
Directions
Make the cake
Cream the butter and sugar together.
Add the egg yolks.
Mix in the sifted flour and baking powder, alternating with the milk.
Pour the batter into a square cake pan.
Bake until done.
Assemble and top
Slice the bananas in half lengthwise, then slice them into quarters.
Place the banana pieces on top of the cake.
Cover the bananas with a thick custard filling.
Whip the egg whites until stiff, gradually adding ¼ cup sugar to make meringue.
Pipe the meringue on top of the cake.
Brown the meringue in the oven.

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 trap air and give the cake a tender, rich crumb.
- Flour
- Forms the cake's structure once mixed with the batter.
- Eggs
- Add structure and richness to the batter, and the whites whip into the meringue.
- Baking powder
- Releases gas in the batter so the cake rises and stays light.
- Milk
- Adds moisture and loosens the batter so it bakes evenly.
- Bananas
- Add moisture, sweetness and fruity flavor to the layered cake.
The step that matters
Whip the egg whites until stiff. Egg whites must be whipped to stiff peaks without deflating; grease or leftover yolk prevents proper foaming, and the meringue will weep or collapse if under-whipped or sugar is added too early.
Swap the banana
How well each one fits the dish's main ingredients (sugar, milk, flour, egg, butter):
- Vanillafits better
- Raisinfits better
- Figfits better
- Bananathe original
Fit is the average pairing score against sugar, milk, flour, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
