Step 1

Combine 1 cup of the blueberries, the maple syrup, water, lemon juice, and vanilla in a small saucepan. Simmer over medium heat for 10 minutes, stirring occasionally.

Add the remaining 1 cup blueberries and cook for 8 minutes, stirring occasionally. Remove from the heat. The mixture will become thick and jammy as it cools.
