Grate orange zest from one orange and keep the zest aside.
Now peel all the oranges carefully. Cut each orange into about 8-10 pieces.
Take a heavy bottom soup pot, which has depth. Add the cut oranges, water, dates and salt. Let it come to a boil on medium heat. Then add the goji berries, lemon juice, mint leaves, orange zest. Simmer for a good 25 min with lid on . Then take the lid off for another 15 min.
You will notice that the volume of the contents reduce, and thickening started to happen. Pectins, naturally present in oranges will cause the thickening.
You can use hand/immersion blender and blend the mixture to a consistency of your preference at this stage.
Now, go ahead add the chia seeds. Stir well. Wait for 6-8 min, before turning the stove off.
Let the jam cool on the counter for 20 min. It will thicken more as it cools with chia seeds presence.
Store in an air tight jar for up to 2-3 weeks in the fridge
Enjoy with toast, or add a spoon on oat meal. Add the tangy fresh jam to sauces, gravies, for added taste.
