Homemade Fresh Blueberry Simple Syrup

0 Combine ingredients. Add fresh blueberries, granulated sugar and water to a small saucepan over medium heat. Stir gently to combine.
1 Simmer until blueberries break down. Bring to a gentle boil, then reduce heat to medium-low. Let it simmer, stirring occasionally and pressing the blueberries with the back of a spoon, until they've completely softened and the syrup is a deep purple.
2 Add lemon, cinnamon and vanilla. Remove from heat and stir in fresh lemon juice, vanilla and cinnamon.
3 Strain and cool. Pour the syrup through a fine mesh strainer into a glass jar or measuring cup, pressing the solids to extract every bit of flavor. Let cool for 15 minutes before serving. If you want a thicker syrup for spooning over ice cream, skip the straining and just allow it to cool.
4 Store. Transfer to a sealed jar and refrigerate. The syrup keeps for up to 2 weeks. Give it a shake before using if it's been sitting.
