Why it works: Vanilla and banana 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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the custard
Beat the egg yolks into the milk in a saucepan.
Add the sugar and mix well.
Moisten the cornstarch with a little cold milk and egg yolks.
Add the moistened cornstarch to the saucepan.
Boil the mixture until thick, stirring constantly.
Assemble the pies
Place a layer of banana slices in each baked pie crust.
Pour the thick filling over the banana slices.
Add another layer of banana slices on top.
Top and bake
Beat the egg whites until stiff peaks form.
Spread the beaten egg whites over the pies.
Bake the pies in a 400°F (200°C) oven for a few minutes until the frosting is lightly browned.

Vanilla and sugar 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
- Egg yolks
- Thicken and enrich the custard filling, giving it body and a rich texture.
- Cornstarch
- Thickens the milk mixture as it boils, giving the filling its set.
- Egg whites
- Whipped into stiff peaks to form the meringue topping that browns in the oven.
- Rich milk
- Forms the liquid base of the custard, adding moisture and richness.
- White sugar
- Sweetens the custard filling and helps the meringue brown.
The step that matters
Boil the mixture until thick, stirring constantly.. Cornstarch only thickens fully once it reaches a boil, but it can scorch or form lumps on the bottom of the pan if not stirred constantly.
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.
“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.
