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 ↓

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Milk
- Forms the liquid base of the custard that sets when thickened.
- Cornstarch
- Thickens the milk mixture into a smooth custard as it heats.
- Egg whites
- Whipped into stiff peaks to form a light topping that adds structure and browning.
- Sponge cake
- Soaks up custard and gives the pudding its soft, layered body.
- Sugar
- Adds sweetness to the custard.
The step that matters
Cook the custard until thickened. Cornstarch only thickens fully when the mixture reaches a simmer while stirred, so stopping early leaves a thin custard that will not set and stir constantly to prevent lumps and scorching on the bottom.
Swap the banana
How well each one fits the dish's main ingredients (milk, sugar, vanilla, egg, wine):
- Figfits better
- Peachfits about as well
- Strawberryfits about as well
- Bananathe original
Fit is the average pairing score against milk, sugar, vanilla, egg, wine. Candidates are from the same food group and used in at least 100 recipes.
