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 ↓
Banana Ice Cream
Ingredients
Directions
Make the base
In a bowl, beat the egg yolks with the sugar until well combined.
Add the cream and milk to the egg mixture and mix well.
In a separate bowl, beat the egg whites until stiff peaks form.
Fold the beaten egg whites and 3 sliced bananas into the cream mixture.
Freeze
Pour the mixture into a freezer and freeze until partly solid.
Stir in the remaining 2 sliced bananas and vanilla, then freeze until firm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the cream and milk and add richness to the custard base.
- Egg whites
- Whipped to stiff peaks, they lighten the mixture and give the ice cream an airy texture.
- Cream
- Adds fat, which makes the ice cream smooth and rich rather than icy.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer.
- Bananas
- Add fruity flavor and moisture to the mixture.
The step that matters
Fold the beaten egg whites into the cream mixture. Stiff egg whites trap air that gives lightness; overmixing them deflates the foam, so the ice cream turns dense and heavy.
Swap the banana
How well each one fits the dish's main ingredients (cream, milk, egg, sugar, vanilla):
- Strawberryfits better
- Figfits about as well
- Coconutfits about as well
- Bananathe original
Fit is the average pairing score against cream, milk, egg, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
