Steps for making sugar free jam.

Step 1

Choose your berries. Here, I am making sugar free strawberry jam. About 12 large berries, or 3 cups, is all you need.

Step 2

Chop berries. They will cook down as they simmer, but the smaller you chop the fewer chunks of fruit you will have in your jam. The choice is entirely up to your personal preference.

Step 3

Measure your berries to ensure you have about 3 cups. It is okay if you have slightly more or less.

Step 4

Add berries to pot over medium high heat.

Step 5

After about 5 minutes your berries should become juicy + begin to bubble. Use a spoon, spatula or potato masher to smash the berries until your desired consistency is reached. I prefer a chunkier jam, so I typically will smash the berries just a bit after cooking for 5 minutes.

Step 6

Add chia seeds + lemon juice after cooking down jam for 5 minutes. Reduce heat to simmer + allow to cook down further, stirring occasionally to ensure chia seeds and lemon juice is fully incorporated. If you have decided to add cinnamon or maple syrup, now’s the time!

Tips for Storing Sugar Free Jam

  • Store jam in airtight, heat proof containers in the fridge. Jam will remain fresh up to 5 days.

    Why chia seeds? Does that thicken the jam?

    • Victoria McMackin Victoria McMackin on Aug 18, 2021

      Chia thickens by becoming mucilaginous and expends when it encounters moisture. So yes, it is a thickening agent.
