In a small pan add the 1 cup granulated sugar and ½ cup mint leaves.
Crush them with the back of a spoon until they are lightly broken up.
Add the water to this mix, place on the stovetop over medium heat. Mix it well and heat until the sugar is dissolved. This will only take a few minutes.
Allow the simple syrup to cool slightly.
Add the blueberries, 1 tablespoon sugar, and lime juice to a small bowl. Mash until the berries are broken up.
Once the simple syrup cools, start assembling.
Add in a few tablespoons of the blueberry mixture, about ¼ cup of simple syrup, and then the sparkling water.
Decorate with more fresh berries, sliced limes, and mint leaves.
Now, sit back and enjoy. You deserve it!
