Place the sugar and water in a small saucepan. Bring to a boil, stir until the sugar has dissolved and let simmer for 5 minutes to make your simple syrup. Let cool.

Stir the lemon juice into the simple syrup.
1 cup lemon juice
For the blueberry vodka lemonade
Add half the blueberries to your cocktail shaker with the vodka and muddle.
3 oz blueberry-infused vodka, 2 tbsp fresh blueberries
Add lemonade and a few ice cubes. Shake vigorously.
3 cups lemonade
Fill the cocktail glasses with the desired amount of ice and strain the liquid into them.
Top with sparkling water. Garnish with lemon slices and blueberries. Cheers!
2 cups sparkling water, 2 lemon slices
Notes
Don't have time to wait around for blueberries to steep in a bottle of vodka? Don't fret! You can buy premade blueberry vodka or mix regular vodka with blueberry syrup. Heck, you can even make the blueberry syrup yourself - it's easy and quicker than infusing vodka.
And of course, if you don't feel like making your own simple syrup for homemade lemonade, you can absolutely use store-bought for that as well. Or if you want to go half-homemade, you can even mix store-bought simple syrup with fresh lemon juice!
