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

What each ingredient does

Plums
Provide the main fruit bulk, pectin, and tart flavor that forms the preserve's body.
Sugar
Sweetens the preserve and, as it boils, thickens it and helps it keep.
Oranges
Contribute bright citrus aroma and acidity from the grated rind to balance the sweetness.
Seedless raisins
Add concentrated sweetness and chewy texture throughout the preserve.
Chopped nuts
Add crunch and a contrasting texture against the soft, jammy fruit.

The step that matters

Boil until thick. Sugar and fruit must be cooked long enough for water to evaporate and pectin to set; stopping early leaves a runny preserve, while overcooking can scorch the sugar and make it stiff.

Swap the nuts

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

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

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