Why it works: Banana and vanilla are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,430 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓

Make the custard
Mix the cornflour smoothly with a little milk.
Put the remaining milk and sugar in a saucepan and bring to a boil.
Add the blended cornflour and milk, and boil for about 10 minutes.

Finish and set
Add the vanilla essence and thinly sliced bananas.
Pour into a prepared mold and let cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornflour
- Starch that swells when heated, thickening the milk into a smooth custard.
- Egg yolks
- Proteins that set on gentle heat, adding richness and further thickening the custard.
- Milk
- Forms the liquid base of the custard, giving body and creaminess.
- Castor sugar
- Adds sweetness and helps soften the set texture of the custard.
- Bananas
- Add flavour and fruity aroma to the finished cream.
The step that matters
Stirring in the egg yolks over low heat. If the yolks get too hot too fast they can scramble into lumps. Cooling the mixture slightly first and keeping the heat low lets the yolks thicken it smoothly.
Swap the banana
How well each one fits the dish's main ingredients (milk, sugar, egg, vanilla):
- Figfits better
- Peachfits about as well
- Blueberryfits about as well
- Bananathe original
Fit is the average pairing score against milk, sugar, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
