Why it works: Butter and banana are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 1,536 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Baked Bananas
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Mix melted butter, sugar, and lemon juice in a bowl.
Baste bananas with half of the mixture.
Bake
Bake for 20 minutes, basting with the remaining mixture during baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bananas
- Their soft flesh becomes tender and sweet as it cooks through in the oven.
- Melted butter
- Adds richness and moisture and helps the bananas take on golden color.
- Sugar
- Adds sweetness and caramelizes at oven heat, deepening color on the surface.
- Lemon juice
- Adds acidity that brightens the flavor and balances the sweetness.
The step that matters
Basting during baking. Basting with the butter, sugar, and lemon mixture keeps the bananas moist and builds a glossy, caramelized coating. Holding back part of the mixture until baking lets that coating build up while the bananas cook.
Swap the lemon
How well each one fits the dish's main ingredients (butter, sugar, banana):
- Vanillafits better
- Figfits better
- Applefits better
- Lemonthe original
Fit is the average pairing score against butter, sugar, banana. Candidates are from the same food group and used in at least 100 recipes.
