Follow our step-by-step guide on how to make Homemade Plum Jam.

1. Step 1

   Begin by assembling all the essential ingredients for your delightful jam.

2. Step 2

   Carefully inspect six half-pint jars for any cracks and check the rings for rust, discarding any that are defective.

3. Step 3

   Immerse the jars in simmering water to keep them warm while you prepare the jam.

4. Step 4

   Wash new lids and rings in warm, soapy water to ensure they are clean and ready for sealing.

5. Step 5

   In a large pot, combine the chopped plums with water over medium-high heat.

6. Step 6

   Bring this mixture to a vigorous boil, then reduce the heat to medium-low, cover, and let it simmer for five minutes, allowing the flavors to meld beautifully.

7. Step 7

   Stir in the sugar, and if you wish, add a touch of butter to minimize foaming.

8. Step 8

   Raise the heat to high, stirring constantly until the mixture reaches a full, rolling boil.

9. Step 9

   Quickly incorporate the powdered pectin and return to a boil, stirring for one minute.

10. Step 10

    Once done, remove from heat and skim off any foam that has formed on the surface.

11. Step 11

    Carefully ladle the hot jam into your sterilized jars, filling them to within an eighth of an inch from the top.

12. Step 12

    Use a clean knife or thin spatula to gently release any trapped air bubbles by running it around the inside of the jars.

13. Step 13

    Wipe the rims with a damp paper towel to eliminate any residue, then place the lids on top and secure the rings tightly.

14. Step 14

    In a large stockpot, place a rack at the bottom and fill it halfway with water.

15. Step 15

    Bring the water to a boil, then lower the jars into the bubbling water, ensuring they are spaced two inches apart.

16. Step 16

    If needed, add more boiling water to cover the jars by at least one inch.

17. Step 17

    Bring the water back to a rolling boil, cover, and process the jars for ten minutes.

18. Step 18

    After processing, carefully lift the jars from the stockpot and let them rest on a cloth-covered or wooden surface, spaced several inches apart, for twelve to twenty-four hours.
