Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Banana Sponge Pudding
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the sponge
Preheat the oven to 350°F (175°C).
In a bowl, whip the sugar with the eggs until well combined.
Gradually mix in the flour and baking powder.
Add the boiling water and mix until smooth.
Pour the mixture into a well-buttered flat tin dish.
Bake for 30 minutes or until golden and set.
Assemble and serve
Once cooled, cut the sponge into pieces and split them.
Spread the mashed and sweetened bananas between the pieces.
Place the assembled sponge in a deep dish and pour over the rich custard.
Garnish with meringue and serve with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped with the sugar to trap air, giving the sponge its light structure.
- Flour
- Forms the sponge's main structure once it is set by baking.
- Baking powder
- Releases gas during baking so the sponge rises and stays airy.
- Sugar
- Sweetens the sponge and helps stabilise the whipped eggs.
- Bananas
- Add moisture and banana flavour between the sponge layers.
The step that matters
Whipping the sugar with the eggs. Whisking until well combined and airy traps air bubbles that expand in the oven. Under-whipping gives a dense sponge, while the sponge must then be fully set in the oven so it does not collapse when cut and layered.
Swap the banana
How well each one fits the dish's main ingredients (sugar, flour, egg, butter, cream):
- Vanillafits better
- Raisinfits better
- Coconutfits about as well
- Bananathe original
Fit is the average pairing score against sugar, flour, egg, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
