4.9 from 21 reviews

This Slow Cooker Plum Jam recipe captures the rich, sweet-tart flavor of blood plums, slowly simmered to create a luscious homemade jam. Utilizing a slow cooker makes the process easy and hands-off, resulting in a smooth, vibrant jam perfect for spreading on toast or adding to desserts. The addition of lemon zest and juice enhances the plum’s natural brightness, and an optional pectin pack can be added for a thicker consistency.

Ingredients

Scale

Fruits

  • 5.5 lbs (2.5 kg) blood plums, quartered and pitted

Other Ingredients

  • 4.4 lbs (2 kg) sugar
  • Zest and juice of one lemon
  • 1/2 cup (120 ml) water
  • 1.76 oz (50 g) pack of Jamsetta (optional, for thicker jam)

Instructions

  1. Prepare the Plums: Cut the blood plums into quarters, making sure to remove all the stones to avoid bitterness and ensure a smooth jam texture.
  2. Combine Ingredients: Place the quartered plums, sugar, lemon zest, lemon juice, and water into the slow cooker. Stir gently to mix all ingredients well.
  3. Cook on High: Set the slow cooker to high heat and cook with the lid on for 3 hours. Stir occasionally during this time to prevent the mixture from sticking to the sides or bottom.
  4. Cook on Low: After 3 hours, switch the slow cooker setting to low and cook uncovered for an additional hour. Continue stirring occasionally to help reduce excess liquid and thicken the jam.
  5. Blend the Mixture: Use an immersion blender or regular blender to puree the plum mixture to your preferred consistency. For a smooth jam, blend thoroughly; for chunkier texture, blend less.
  6. Optional – Thicken with Jamsetta: If you want a thicker jam, mix half of the Jamsetta pack with some of the pureed fruit, then stir this mixture back into the slow cooker. Cook briefly to allow it to thicken.
  7. Bottle the Jam: Carefully ladle the hot jam into sterilized jars, filling them to just below the rim. Avoid spills on the jar rims to ensure good seals.
  8. Seal and Store: Seal jars tightly while hot and let them cool completely at room temperature. Store the cooled jars in a cool, dark place. The jam can be refrigerated or processed for longer shelf life if desired.

Notes

  • Ensure all jars and lids are properly sterilized to prevent spoilage.
  • You can adjust the sugar amount slightly depending on the sweetness of the plums.
  • If using Jamsetta or any pectin, follow package instructions for best results.
  • The jam will thicken further as it cools.
  • Store opened jam in the refrigerator and consume within 3 weeks.
  • This jam is delicious on toast, yogurt, or as a dessert topping.
