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 Cake
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Mix the sugar and crushed bananas in a bowl.
Add the butter, sweet milk, and beaten eggs, and mix well.
Gradually incorporate about half of the flour, then fold in the remaining flour and baking powder gently.
Pour the batter into two greased cake pans.
Bake and serve
Bake in a moderate oven at 350°F (175°C) until a toothpick comes out clean.
Spread with whipped cream or cream icing before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Eggs
- Bind the batter and add structure and richness to the crumb.
- Baking powder
- Releases gas during baking, helping the cake rise and turn light.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Crushed bananas
- Add moisture and natural sweetness, along with banana flavor.
- Granulated sugar
- Sweetens the cake and helps keep it moist and browned at the edges.
The step that matters
Folding in the flour and baking powder. Adding flour in portions and folding gently keeps gluten development limited, so the cake stays tender rather than tough. Overmixing after the flour goes in can make the crumb dense and chewy.
Swap the banana
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Bananathe original
Fit is the average pairing score against sugar, butter, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
