Why it works: Banana and vanilla are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,430 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Banana Pie
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 the crust
Preheat the oven to 350°F (175°C).
Line a deep pie tin with a rich crust.
Slice the bananas and place them in the pie crust.
Make the custard
Heat the milk to boiling point.
In a bowl, beat the egg yolks, then mix in the sugar and flour.
Add the beaten yolk mixture to the boiling milk and cook until thick.
Once slightly cooled, stir in the vanilla and pour the mixture over the bananas.
Top and bake
Beat the egg whites until stiff, then add the powdered sugar and spread over the pie.
Bake in the oven until the top is browned.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Bananas
- Provide the main fruit flavor and soft texture under the custard.
- Milk
- Forms the base of the custard that sets when cooked.
- Eggs
- Egg yolks thicken the custard, and whites whipped into a meringue topping for structure.
- Sugar
- Sweetens the custard and helps the meringue hold its shape.
- Flour
- Thickens the custard so it holds together when cut.
The step that matters
Cooking the yolk mixture into the boiling milk. Egg yolks can scramble if added too quickly to hot liquid. Adding the yolks gradually while stirring, then cooking until thick, gives a smooth custard.
Swap the banana
How well each one fits the dish's main ingredients (milk, sugar, flour, egg, vanilla):
- Raisinfits better
- Figfits better
- Blueberryfits better
- Bananathe original
Fit is the average pairing score against milk, sugar, flour, egg, vanilla. 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.
