- 4 cups fresh or frozen blueberries
- 1/2 cup honey
- 1/4 cup fresh lemon juice
- 1/2 teaspoon cinnamon (optional)
- Rinse the blueberries and remove any stems or leaves.
- In a medium-sized saucepan, combine the blueberries, honey, and fresh lemon juice.
- Heat the mixture over medium-high heat, stirring frequently, until the blueberries begin to break down and release their juices.
- Reduce the heat to low and let the blueberries simmer for about 20-25 minutes, stirring occasionally, until the mixture thickens and reduces by about one-third.
- Remove the saucepan from the heat and let the blueberry jam cool for a few minutes.
- Using an immersion blender or a food processor, puree the blueberry mixture until you have a smooth and uniform consistency.
- If using, stir in the cinnamon.
- Pour the blueberry jam into clean glass jars, leaving about 1/2 inch of headspace at the top.
- Let the blueberry jam cool to room temperature, then cover the jars with their lids and store them in the refrigerator for up to 3 weeks.
Enjoy your delicious and healthy blueberry jam, perfect for spreading on toast, pancakes, or yogurt!
