Why it works: Vanilla and banana 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 ↓
Banana Snowball
Ingredients
Directions
Make the custard
In a double boiler, combine milk, sugar, egg yolks, salt, butter, and cornstarch.
Stir over heat until thick, then add vanilla flavoring and let cool.
Prepare the topping
Beat egg whites to stiff peaks, then mix in 2 tablespoons of sugar.
Assemble and serve
Slice bananas and place them in a dish.
Pour the custard over the bananas and top with the egg white mixture shaped like snowballs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness as they set with gentle heat.
- Egg whites
- Whip into stiff peaks to form a light, airy topping.
- Cornstarch
- Thickens the milk mixture so the custard becomes smooth and firm when cooked.
- Milk
- Forms the liquid base of the custard.
- Bananas
- Provide the fruit base and sweet, soft flavor under the custard.
The step that matters
Stir the custard over heat until thick. Egg yolks and cornstarch thicken only with gentle, steady heat. Too much heat can curdle the eggs, while too little leaves the custard runny.
Swap the walnut
How well each one fits the dish's main ingredients (milk, sugar, egg, butter, vanilla, banana):
- Almondfits better
