Combine all of the above ingredients except the chia seeds in a thick bottom saucepan and cook on slow flame.
Keep stirring to avoid the dates mixture from sticking to the bottom.
Cook for about 20 to 30 minutes or till the water has completely dried up and dates have softened and turned pulpy.
Add the chia seeds and give it a nice stir again.
Cool the cooked jam and transfer to a sterilized and clean glass container.
Store in the refrigerator.
