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 ↓

Flour and milk 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
- Eggs
- Provide structure in the cake and thicken the custard as they set with heat.
- Flour
- Forms the structure of the cake crumb as its starch and proteins set during baking.
- Sugar
- Sweetens the cake and adds tenderness to the crumb.
- Baking powder
- Releases gas during baking so the cake rises and turns light.
- Milk
- Forms the liquid base of the custard, adding richness and body.
- Cornstarch
- Thickens the custard as its starch swells and sets when heated.
The step that matters
Cook the custard until thickened. Cornstarch only thickens fully when the mixture reaches a boil and is stirred, and eggs can curdle if overheated. Stop cooking once it is thick and smooth.
Swap the banana
How well each one fits the dish's main ingredients (egg, sugar, flour, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Bananathe original
Fit is the average pairing score against egg, sugar, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
