Why it works: Milk and banana are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 1,470 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. 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
Heat the milk in a saucepan.
Mix ¾ cup sugar, flour, and salt in a bowl, then stir into the milk.
Add the beaten egg yolks and cook until thick.
Let the custard cool.
Assemble and bake
Slice the bananas into the cooled pie crust.
Pour the custard over the bananas.
Beat the egg whites until stiff.
Gradually add 3 tablespoons sugar to the egg whites.
Spread the meringue over the custard.
Brown in the oven at 400°F (200°C).

Milk and flour barely smell alike, yet cooks put them together in 78,219 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 the milk mixture into a custard as they cook.
- Egg whites
- Whipped into meringue, they provide the light, airy topping that browns in the oven.
- Sugar
- Sweetens the custard and meringue, and helps the meringue hold its structure.
- Flour
- Stabilizes the custard so it thickens without becoming runny.
- Bananas
- Provide the fruity flavor and soft texture layered under the custard.
The step that matters
Cook the custard until thick. Egg yolks thicken as they heat, but overheating can scramble them. Cooking gently until the custard coats a spoon gives a smooth filling that sets properly once cooled.
Swap the banana
How well each one fits the dish's main ingredients (milk, sugar, flour, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Bananathe original
Fit is the average pairing score against milk, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
