Place all the ingredients, except for the chia seeds, into a pot on the stovetop and turn to medium heat
Allow the ingredients to come to a boil and simmer for 10-15 minutes, until the fruit is softened and breaking apart.
Remove the pot from the heat and using your immersion blender blend the ingredients until you have the texture you desire (I like to have a few chunks left).
Stir in the chia seeds and allow the fruit mixture to sit for at least 20 minutes (this thickens the jam).
Serve and enjoy!
Notes
You can swap the plums for other fruit such as blueberries, raspberries or blackberries.
