2 C fresh blueberries
¾ C granulated sugar
⅔ C freshly squeezed lemon juice
4 C cold water, divided
Lemon slices and blueberries to garnish, if desired
Place the blueberries, sugar and 1 cup water in a blender. Blend on medium-high speed for about 1 minute, until the blueberries are completely pureed. Strain the blueberry puree through a fine mesh sieve (or skip this step if you don't mind small pieces of blueberry in your lemonade).
Combine the blueberry puree with lemon juice and the remaining 3 cups of water. Add more water, if desired. Stir well and chill. Serve over ice.
