Why it works: Banana and milk 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 ↓

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 custard filling as they set when heated.
- Flour
- Stabilises the paste and helps the filling thicken when cooked in milk.
- Egg whites
- Whipped into a light topping that adds volume and a soft texture.
- Sugar
- Sweetens the filling and helps stabilise the egg yolk mixture.
- Bananas
- Provide the fruit layer and their flavour and softness to the pie.
The step that matters
Pour the paste into the boiling milk and cook until thickened. Adding the egg and flour paste gradually to hot liquid, while stirring, prevents lumps and curdling. The filling must be cooked long enough for the starch to thicken fully, but not so long that the egg yolks scramble.
Swap the banana
How well each one fits the dish's main ingredients (sugar, milk, egg, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Bananathe original
Fit is the average pairing score against sugar, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
