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

What each ingredient does

Pineapple
Provides the main fruit flavor and sweetness, and its juice makes up the body of the loaf.
Knox gelatin
Sets the mixture so it holds its loaf shape when cooled.
Whipped cream
Adds fat and a light, airy texture to the set loaf.
Egg whites
Whipped to stiff foam, they add lightness and airy structure.

The step that matters

Fold in whipped cream and egg whites when the mixture is only partly set. If the mixture is too warm, the cream and egg whites deflate and lose their air; if it has set too far, they will not blend evenly. Folding at the point of just beginning to thicken keeps the loaf light and uniform.

Swap the pineapple

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

  1. Vanillafits better
  2. Strawberryfits better
  3. Raisinfits about as well
  4. Pineapplethe original

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