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).
Assemble the tart
Make a crust using flour and fresh batter.
Line a dish with the crust.
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 white sugar.
Bake
Bake for 20 minutes or until golden brown.

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 tart together.
- Apples
- Provide the main fruit body and tartness as they soften during baking.
- Bananas
- Add soft texture and natural sweetness to the fruit filling.
- Sugar
- Sweetens the fruit and helps it caramelize at the edges.
- Melted butter
- Adds fat for richness and helps the top brown evenly.
The step that matters
Brush melted butter over the top and sprinkle with white sugar. Butter and sugar on the surface promote browning and a crisp, golden top. Covering the fruit fully with the crust before this step keeps the filling moist while it bakes.
Swap the apple
How well each one fits the dish's main ingredients (flour, milk, banana, sugar, syrup, butter):
- Vanillafits better
- Figfits better
- Peachfits about as well
- Applethe original
Fit is the average pairing score against flour, milk, banana, sugar, syrup, butter. 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.
