Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. 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 filling
Preheat the oven to 350°F (175°C).
Mix sugar and flour in the bottom of the pie crust.
Combine vinegar and water, then add to the mixture.
Add butter and mix well.
Bake and finish
Bake until set.
Slice bananas and layer them in the pie.
Top with meringue and brown slightly in the oven.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Sugar
- Adds sweetness and helps give the filling its body.
- Flour
- Thickens the filling and gives it structure as it sets.
- Vinegar
- Adds acidity that brightens the flavour and balances the sweetness.
- Butter
- Adds fat for richness and a softer, more tender texture.
- Bananas
- Provide the main fruit flavour and sweetness in the layers.
- Meringue
- Forms the topping and browns in the oven for colour.
The step that matters
Top with meringue and brown slightly in the oven. Meringue browns quickly because its sugar caramelises at high heat. Watch it closely, since a few minutes too long can scorch the topping before the pie is heated through.
Swap the banana
How well each one fits the dish's main ingredients (sugar, flour, vinegar, butter):
- Raisinfits better
- Vanillafits better
- Figfits better
- Bananathe original
Fit is the average pairing score against sugar, flour, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
