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 ↓
Cream Banana Nut 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.
Make the filling
In a double boiler, bring 1 ½ pints of milk to a boil.
In a separate bowl, mix together 1 cup of sugar, 3 egg yolks, 2 tablespoons of cornstarch, and 3 tablespoons of flour.
Add the mixture to the boiling milk and stir continually until well cooked.
Assemble and bake
Arrange sliced bananas in the bottom of the pie crust and pour the filling over them.
Sprinkle the top with walnut meats.
Prepare meringue and spread it over the top of the pie.
Brown the meringue in a 350°F (175°C) oven.

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 to the filling.
- Cornstarch
- Thickens the milk mixture as it cooks into a smooth custard.
- Flour
- Adds additional thickening to help the filling set.
- Milk
- Forms the liquid base of the custard filling.
- Sugar
- Sweetens the filling and balances the flavor.
The step that matters
Stirring the filling while it cooks. Starch-thickened custard can scorch on the bottom or form lumps if it is not stirred constantly. Cooking it until well thickened lets the starch gelatinize fully, so the filling sets properly when cooled.
Swap the walnut
How well each one fits the dish's main ingredients (milk, sugar, egg, flour, vanilla, banana, meat):
- Almondfits better
- Chestnutfits better
- Hazelnutfits about as well
- Walnutthe original
Fit is the average pairing score against milk, sugar, egg, flour, vanilla, banana, meat. 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.
