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 ↓
Banana Custard
Ingredients
Directions
Prepare
Slice the bananas and place them in a deep dish.
Heat the milk in a saucepan until boiling.

Pour the mixture over the bananas, stirring gently to combine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bananas
- Provide the main flavor and sweetness of the dish.
- Milk
- Forms the liquid base that the custard thickens into.
- Egg
- Thickens the custard as it heats and adds richness.
- Sugar
- Adds sweetness that balances the banana flavor.
- Cornstarch
- Thickens the milk when heated, giving the custard body.
The step that matters
Stirring the egg mixture into the hot milk. The egg can scramble if it meets very hot milk without being stirred well. Blending the egg with a little milk first and stirring constantly helps it blend smoothly, while the starch thickens the custard as it boils.
Swap the banana
How well each one fits the dish's main ingredients (milk, egg, sugar):
- Vanillafits better
- Figfits better
- Raisinfits better
- Bananathe original
Fit is the average pairing score against milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
