Place the strawberries and 4 tablespoons maple syrup (or honey) in a medium saucepan or pot.
Use a potato masher to mash the strawberries into medium-size chunks.
Place the saucepan on the stovetop and turn to high heat. Once it starts to boil, reduce the heat to medium low and simmer for 10 minutes.
Once the mixture is done simmering, remove it from heat and stir in the chia seeds. Taste and add an additional tablespoon or two of maple syrup or honey if needed. Allow the jam to cool for 10 minutes, then pour it into a mason jar.
Place the jar in the fridge and allow to cool completely before serving.
Notes
This recipe can be used with blueberries and raspberries, but you'll probably want to increase the amount of sweetener used. I recommend adding it in 1 tablespoon increments until it reaches the sweetness level you prefer.
