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

What each ingredient does

Blue plums
Provide the main fruit body and natural pectin that helps the preserve thicken as it cooks.
Granulated sugar
Sweetens the preserve and helps set its thick, spreadable texture while preserving it.
Pecans
Add crunch and richness that contrast with the soft, jammy fruit.
Seeded raisins
Add concentrated sweetness and chewy texture as they soften during cooking.
Orange juice
Adds acidity and bright citrus flavor that balances the sugar.

The step that matters

Boiling for 20 minutes. Boiling long enough lets water evaporate and sugar concentrate, which helps the fruit thicken into a preserve. Too short a boil leaves it runny, while overcooking can make it stiff or scorch on the bottom of the pot.

Swap the pecans

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

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Pecansthe original

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