The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

  1. Vanilla + bananatop 1% of all pairs

    Shared aroma: ethyl isobutyrate (fruity, ethereal).

  2. Milk + vanillatop 5% of all pairs

    Shared aroma: ethyl caproate (fruity, apple peel).

    Shared aroma: 2,3-butanedione (butter, sweet).

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):

  1. Coconutfits better
  2. Figfits better
  3. Strawberryfits about as well
  4. 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.
