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 ↓
Ice Cream
Ingredients
Directions
Make the custard
Prepare the custard by heating the milk and whisking in the eggs and corn starch until thickened.
Sweeten the custard to taste and add vanilla extract.
Freeze and finish
Combine the custard with the heavy cream.
When the mixture begins to freeze, stir in the sliced bananas.
Continue freezing until fully set.

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
- Heavy cream
- Adds fat and richness, giving the ice cream a smooth, creamy texture.
- Eggs
- Egg proteins thicken the custard and add richness to the base.
- Corn starch
- Thickens the custard and helps keep the ice cream smooth and less icy.
- Milk
- Forms the liquid base of the custard and adds dairy flavor and body.
- Bananas
- Add fruity flavor and sweetness, and fold in as sliced pieces for texture.
The step that matters
Stir in the bananas as the mixture begins to freeze. Adding sliced bananas too early lets them freeze hard and unevenly, while adding them once the base is partly set keeps them suspended and evenly distributed through the ice cream.
Swap the banana
How well each one fits the dish's main ingredients (cream, milk, egg, corn, sugar, vanilla):
- Coconutfits better
- Figfits better
- Strawberryfits about as well
- Bananathe original
Fit is the average pairing score against cream, milk, egg, corn, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
