Why it works: Apple and banana match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 435 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓
Banana and Apple Tart
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.
Prepare
Preheat the oven to 350°F (175°C).
Make a crust using flour and butter.
Line a dish with the crust.
Assemble
Slice the apples and bananas, then place them in the dish.
Add sugar and syrup to the fruit.
Cover the fruit with the crust.
Brush melted butter over the top and sprinkle with sugar.
Bake
Bake for 20 minutes or until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- All-purpose flour
- Forms the structure of the crust that holds the fruit.
- Butter
- Adds richness and tenderness to the crust and browns the top when brushed on.
- Apples
- Provide the main fruit filling that softens and holds its shape when baked.
- Bananas
- Add soft texture and sweetness to the fruit filling.
- Sugar
- Sweetens the filling and helps the topping brown and caramelize.
- Syrup
- Adds sweetness and moisture to the fruit filling.
The step that matters
Covering the fruit with the crust. Sealing the fruit fully under the crust traps moisture and steam so the filling cooks through, while the exposed top still needs to brown properly in the oven.
Swap the apple
How well each one fits the dish's main ingredients (flour, butter, banana, sugar, syrup):
- Vanillafits better
- Figfits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against flour, butter, banana, sugar, syrup. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
