Instead of the large amounts of sugar needed to set traditonal jams, here the amazing properties of chia seeds are used to make a jam-like fruity spread with little or no sugar.
Use fresh or frozen fruit, replacing the blueberries with raspberries or strawberries if you like.
If using fresh fruit, wash and remove any stems.
Put the blueberries in a saucepan over medium heat and bring to a simmer.
When they start to release their juices, use a fork or potato masher to squash the berries so they release more liquid.
Continue simmering until you have a thickish puree (approx 10 minutes)
Taste and add sweetener if liked and/or a squeeze of lemon to sharpen.
Stir in the chia seeds and keep stirring while the jam thickens (2 minutes).
Take off the heat and transfer the jam to a clean, dry jar.
Set aside to cool. The jam will continue to thicken as it cools.
When cold, put a lid on the jar and store in the fridge.
Use within 1 week.
