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 ↓
Baked Apple and Bananas
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Prepare the apples by coring them, making the hole large enough to hold half a banana.
Stuff each apple with half a banana.
Sprinkle 1 teaspoon of sugar over each apple.
Squeeze a few drops of lemon juice on top.
Bake
Bake the apples in the preheated oven until tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the firm fruit that softens into tender, spoonable flesh as the cell walls break down with heat.
- Bananas
- Add sweetness and a soft, creamy texture that fills the cored centre as it warms.
- Sugar
- Adds sweetness and helps the cut surfaces brown and caramelize slightly in the oven.
- Lemon juice
- Adds acidity that brightens the flavour and helps slow browning on the cut fruit.
The step that matters
Bake until tender. Heat softens apple by breaking down its pectin and cell walls. Too short a bake leaves the apple firm and starchy, while too long turns it mushy and collapses the shape.
