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 Cream Pie
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the crust
Preheat the oven to 400°F (200°C).
Line a pie pan with the crust and bake until golden.
Cover the bottom of the baked crust with the banana slices.
Make the custard
In a double boiler, combine milk, cornstarch dissolved in a little milk, egg yolks, and vanilla extract.
Boil until thickened, then pour the custard into the pie crust.
Top and bake
Beat the egg whites until stiff, adding sugar if desired, then spread over the custard.
Return to the oven until the top is golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness and a yellow colour to the filling.
- Cornstarch
- Thickens the milk mixture into a smooth, sliceable custard as it heats.
- Egg whites
- Whipped into a stiff foam that forms a light topping and browns in the oven.
- Milk
- Forms the liquid base of the custard that the cornstarch and yolks thicken.
- Bananas
- Add fruity sweetness and flavour layered beneath the custard.
The step that matters
Boil until thickened. Cornstarch only thickens fully once it reaches a boil, and the yolks must be cooked through without scrambling. Stirring constantly over direct heat or a double boiler keeps the custard smooth and properly set.
Swap the banana
How well each one fits the dish's main ingredients (milk, egg, vanilla, sugar):
- Figfits better
- Peachfits about as well
- Blueberryfits about as well
- Bananathe original
Fit is the average pairing score against milk, egg, vanilla, sugar. Candidates are from the same food group and used in at least 100 recipes.
