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

What each ingredient does

Wild plums (or grapes)
Provide the fruit that is cooked until clear and packed in the syrup.
Brown sugar
Sweetens the syrup and thickens it as it boils down.
Vinegar
Adds acidity that gives the preserve a sharp, tangy balance against the sugar.

The step that matters

Boil syrup until thick, then pour over fruit and seal. Syrup must be boiled down enough to reach a thick, sugar-rich consistency so it preserves the fruit and sets properly when sealed. Pouring over fruit before it thickens leaves a thin liquid that spoils more easily.

Swap the plum

How well each one fits the dish's main ingredients (sugar, vinegar, cinnamon, cassia, allspice, clove):

  1. Vanillafits about as well
  2. Figfits about as well
  3. Orangefits about as well
  4. Plumthe original

Fit is the average pairing score against sugar, vinegar, cinnamon, cassia, allspice, clove. Candidates are from the same food group and used in at least 100 recipes.
