Place all ingredients into a metal pot and bring to a boil.
Reduce heat slightly so the contents of the pot don't splatter all over your stove but still bubble in the pot.
Stir constantly! The chia seeds burn on the bottom of the pot very easily. So keep stirring (I had to change pots halfway through because the seeds burned so easily).
Stir and boil until the mixture has reduced by half and has thickened into a gel-like consistency. Again, it will not be as thick as jam but will definitely thicken.
Pour into a clean glass jar and allow to cool for 1 hour. Place in the fridge overnight to continue cooling.
Notes
There is no way for me to know exactly how far you will boil down the spread, and therefore I have no idea how many servings this will end up being for you. The below numbers are for the entire recipe. Simply divide by the number of servings you end up with. Please note that the nutrition data here is a ballpark figure. Exact data is not possible.
