Using the back of a fork or a potato masher, mash them down a bit to break them up even more.
Add in the maple syrup and lemon juice. Stir to combine.
Let simmer for 5-6 minutes and then add in the chia seeds. Stir to combine.
Let simmer for another 2-3 minutes. The jam will start to thicken up.
Remove from heat an let the jam cool.
Use on toast, pancakes, muffins, crackers, etc.
