First, I toss the blueberries and dried lavender into the shaker.
I muddle them gently—enough to release juice and flavor, but not so much that it gets messy.
Next, I add vodka, simple syrup, lemon juice, and a scoop of ice.
I close up the shaker and give it a good, hard shake for about 15 seconds.
Then I strain the mix into a glass filled with fresh ice.
I top it off with club soda or sparkling water, then stir gently with a spoon to mix in the bubbles.
If I’m feeling fancy, I’ll add a mint sprig or a lemon slice on top.
