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

What each ingredient does

Cherries
Provide the main fruit flavor and soft, juicy texture once preserved.
Plums
Add fruit body and tartness that balances the sugar in the filling.
American apples
Contribute firm pieces and pectin that help the preserved fruit hold its shape.
Loaf sugar
Sweetens the fruit and draws out its juices, helping to preserve it.

The step that matters

Sealing the jars before boiling. The bladder covers must be tied down tightly so that water cannot enter the jars during the long boil. Water entering would dilute the fruit and spoil the preserve, so a secure seal protects the contents.

Swap the plum

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

  1. Pearfits better
  2. Vanillafits better
  3. Apricotfits about as well
  4. Plumthe original

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