Ingredients

  • 4 cups fresh ripe plums, washed, pitted, and finely chopped
  • 2 cups granulated sugar
  • 1 package (1.75 oz) fruit pectin made for freezer jam
  • 2 tablespoons fresh lemon juice
  • 3/4 cup water

Instructions

  1. Finely chop the plums and measure exactly 4 cups into a large mixing bowl.
  2. Add the lemon juice to the plums and stir well to combine.
  3. In a separate bowl, mix the granulated sugar and fruit pectin until evenly distributed.
  4. Gradually stir the sugar-pectin mixture into the plums, stirring continuously for about 2–3 minutes until the sugar starts to dissolve.
  5. Warm the water in a small saucepan just until warm, not boiling.
  6. Slowly pour the warm water into the plum mixture while stirring constantly.
  7. Continue stirring for another 2–3 minutes until the jam thickens slightly.
  8. Spoon the jam into clean, freezer-safe jars, leaving about 1/2 inch of space at the top.
  9. Let the jars sit at room temperature for several hours or overnight until the jam sets.
  10. Transfer the jars to the freezer for long-term storage.

Notes

  • Sweetness can be adjusted slightly depending on the ripeness of the plums.
  • Do not significantly reduce sugar, as it affects the jam’s ability to set.
  • Plum skins are left on for better color and flavor.
  • Optional flavor additions include cinnamon, cardamom, or vanilla extract.
  • Frozen plums can be used if fully thawed and well-drained.
