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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Cook the sweet milk, sugar, vanilla, egg yolks, and flour together in a double boiler until thick.
Make the crust
Mix the flour, ice water, and lard for the pie crust.
Bake the crust until golden.
Assemble and bake
Layer sliced bananas in the baked crust.
Pour the thick filling over the bananas.
Beat the egg whites with sugar until stiff.
Spread the stiff egg whites on top of the pie.
Bake the pie in a moderate oven at 350°F (175°C) until the topping is browned.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Sweet milk
- Forms the liquid base of the custard filling.
- Egg yolks
- Thicken the custard filling as it cooks with heat.
- Flour
- Thickens the filling and gives structure to the pie crust.
- Lard
- Adds fat that keeps the pie crust tender and flaky.
- Egg whites
- Beaten to stiffness, they form a light topping that browns in the oven.
- Sugar
- Sweetens the filling and helps the meringue topping brown.
The step that matters
Cook the filling until thick. Egg yolks and flour thicken the custard only when it is heated enough. Cooking gently in a double boiler helps prevent the eggs from scrambling or curdling, which would leave the filling grainy instead of smooth.
Swap the banana
How well each one fits the dish's main ingredients (milk, sugar, vanilla, egg, flour):
- Raisinfits better
- Figfits better
- Blueberryfits better
- Bananathe original
Fit is the average pairing score against milk, sugar, vanilla, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
