  • 10 lbs plums ripe
  • 4 1/2 cups white sugar
  • Zest of 1 lemon
  • Juice of 1 lemon
  • mason jars with lids


  • Rinse the plums, halve them, and remove the pits.
  • Add the plums to a large mixing bowl and top with the sugar, stir to coat and let them sit for 2 hours.
  • Transfer the mixture into a large cooking pot.
  • Over medium heat, bring it to a boil uncovered, and stir occasionally.
  • Add lemon juice and lemon zest.
  • Boil until the mixture is bubbling uniformly.
  • Simmer for 2 hours on low heat, then turn off the heat. Cool to room temperature. Repeat this step 4 times. I usually get this done over a period of 2 days, or I start early in the morning.
  • Last time bringing it to a boil, make sure to stir frequently to prevent scorching and do NOT cool it.

Sterilize The Jars:

  • Wash the jars and the lids with warm water and soap then let them dry completely, this is important.
  • Boil the lids for 5 min.


  • Transfer the hot jam into the jars using leaving about 1/2″ space.
  • Screw the lids on to hold a tight seal in place but don't over-tighten them.
  • Place the jars into the canning pot and cover with 2 inches of water. Bring to a boil and process for 15 minutes.
  • Remove from the pot and leave at room temperature undisturbed for 24 hours.
  • After 24 hours, check that the seal has formed by pushing down on the center of the lid, it should not move at all.
  • If the seal does not form, refrigerate jam and enjoy within 3 months.
