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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make a crust using flour and butter.
Line a dish with the crust.
Assemble and bake
Layer the sliced apples and bananas in the dish.
Sprinkle sugar and syrup over the fruit.
Cover the fruit with the remaining crust.
Brush melted butter on top and sprinkle with sugar.
Bake for 20 minutes or until golden.

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.
- Apples
- Provide the main fruit body and tart texture when baked.
- Bananas
- Add soft texture and natural sweetness to the filling.
- Sugar
- Sweetens the fruit and helps the top caramelise to a golden colour.
- Syrup
- Adds sweetness and moisture that blends into the fruit as it bakes.

- 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.
