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

What each ingredient does

Plums
Firm, slightly unripe fruit holds its shape through repeated heating and syrup soaking.
Vinegar
Adds sharp acidity that balances the sweetness and helps preserve the pickles.
Sugar
Adds sweetness and thickens the syrup that coats and sweetens the plums.
Cinnamon
Contributes warm, sweet aroma to the syrup.
Cloves
Contributes strong, warm aroma and flavour to the syrup.

The step that matters

Heating the jars over three mornings. Repeated gentle heating lets the hot syrup slowly penetrate firm plums without breaking them down, while the full boil on the last day heats the fruit and syrup thoroughly before sealing.

Swap the plum

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

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

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