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

What each ingredient does

Heavy cream
Whipped to stiff peaks, it forms the airy, light body of the dessert.
Egg whites
Beaten to stiff peaks, they add lightness and help the mixture hold its volume.
Marshmallows
Melt slightly into the cream, adding sweetness and a soft, chewy texture.
English walnuts
Add crunch and a contrasting texture to the soft mixture.

The step that matters

Fold the beaten egg whites into the whipped cream. Folding gently keeps the air trapped in the whites and cream. Stirring vigorously deflates the foam, leaving a dense, heavy result instead of a light one.

Swap the banana

The recipe marks banana as optional. How well each one fits the dish's main ingredients (walnut, egg, cream, sugar):

  1. Vanillafits better
  2. Figfits better
  3. Coconutfits better
  4. Bananathe original

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