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

What each ingredient does

Plums
Provide the fruit base and much of the bulk of the preserve.
Sugar
Sweetens the preserve and, as it thickens during boiling, helps it set.
Seeded raisins
Add concentrated sweetness and body to the preserve.
Orange juice
Adds acidity and brightness that balance the sugar.
Orange rind
Adds aromatic oils that give a citrus fragrance and flavour.

The step that matters

Boil the mixture carefully. Sugar-rich fruit mixtures scorch easily on the bottom of the pan because the sugar caramelises at high heat. Stirring and moderate heat prevent burning and a bitter taste.

Swap the plum

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

  1. Vanillafits better
  2. Figfits better
  3. Lemonfits better
  4. Plumthe original

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