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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Gelatin
Sets the liquid into a jelly that holds the airy banana mixture.
Banana pulp
Adds banana flavor and body to the jelly as it sets.
Egg whites
Whipped into foam, they lighten the mixture into a snow-like texture.
Sugar
Sweetens the jelly and helps balance the lemon's tartness.
Lemon juice
Adds acidity that brightens the banana flavor.

The step that matters

Beat until foamy. Beat the jelly only while it is partially set. If it is too liquid, the foam will not hold; if it is too firm, it will not whip smoothly into the banana pulp.

Swap the banana

How well each one fits the dish's main ingredients (gelatin, sugar, lemon, egg):

  1. Vanillafits better
  2. Orangefits better
  3. Raspberryfits better
  4. Bananathe original

Fit is the average pairing score against gelatin, sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
