For one cocktail:
- 2 oz vodka
- 1/4 cup fresh blueberries
- 1/2 oz simple syrup
- 1/2 oz fresh lemon juice
- Ice
- Sparkling water
- Extra blueberries and lemon slice for garnish
Use good quality vodka for the best taste. Fresh blueberries work better than frozen. You can adjust the simple syrup to make it more or less sweet.
