Prepare the blueberries: Toss blueberries into the shaker or jar and muddle gently. You want them crushed, but not totally pureed.
Add the base: Pour in vodka, lemon juice, and simple syrup. No need to overthink it.
Shake well: Add ice, secure the lid, and give it a good shake for 15-20 seconds. You want it nice and chilled.
Strain the mixture: Pour through a fine mesh strainer into an ice-filled glass, catching the blueberry pulp and seeds.
Add bubbles: Top with sparkling water and stir gently with a bar spoon. Don’t go wild—you want to keep the fizz.
Garnish: Finish with a lemon wheel, a few blueberries, and a sprig of mint if you’re feeling fancy.
