  • Blueberries
    150 g
  • Water
    50 mL
  • Maple Syrup
    10 g
  • Ground Flaxseeds
    15 g
  • Lemon Juice
    10 mL

Recipe Instructions

step 1

In a deep pan add blueberries, water, and maple syrup.

Simmer at medium heat for about 15 minutes or until the berries have softened.

Then mash them with the back of a spoon or with a potato masher to release their juice.

step 2

Stir in the flaxseeds and lemon juice and cook the jam for further 3 minutes and then remove from the heat.

The flaxseeds will absorb the fruit juice and make the jam dense.

step 3

Now, transfer the hot jam into a sterilised jar, seal, and keep upside down for 5 minutes before storing it away to remove excess air in the jar.

Store the jam in the fridge and remember that it will get thicker as it cools down.

Enjoy your homemade sugar free blueberry jam!


  • Instead of maple, you can use honey or agave syrup.

  • You can stir in chia seeds or more flaxseeds for a thicker consistency.

  • As this jam is sugar-free, it won't last as long as the sugared ones, so we recommend you store it for up to 2 months and consume it within two weeks after opening.
