In a medium saucepan, combine 2 cups of fresh blueberries, 1 cup of water, and your preferred sweetener (like Stevia or Erythritol). Stir gently to ensure the blueberries are evenly dispersed in the water.

Once boiling, reduce the heat to low and let the mixture simmer uncovered for about 10 to 15 minutes until the blueberries burst and release their juice.

Remove the saucepan from heat and strain the syrup through a fine mesh sieve into a bowl, using the back of a spoon to press the blueberries.

Allow the freshly made blueberry syrup to cool to room temperature, then transfer to an airtight container for storage.
