01 - Place berries in a medium saucepan over medium heat. Cook, stirring occasionally, for approximately 5 minutes until berries soften and release their natural juices.
02 - Mash berries using a fork or potato masher until reaching preferred consistency, whether chunky or smooth.
03 - Stir in maple syrup or honey, chia seeds, vanilla extract, and lemon juice until evenly distributed throughout the mixture.
04 - Remove from heat and let stand for 5 minutes, stirring occasionally. The mixture will thicken as chia seeds absorb the released liquids.
05 - Taste the mixture and add additional sweetener if needed to achieve desired sweetness level.
06 - Transfer jam to a clean jar, allow to cool completely, then seal and refrigerate. Store for up to 1 week.
