A refreshing and vibrant martini with a citrus twist and a hint of blueberry.
Prepare the rim of the martini glass by moistening it with a lemon wedge and dipping it into a plate of granulated sugar.
Chill the glass in the freezer beforehand for a frosty effect.
In a shaker filled with ice, combine the vanilla-flavored vodka, limoncello, and a handful of fresh blueberries.
Muddle the blueberries slightly in the shaker for a stronger berry flavor.
Shake the mixture well and strain it into the prepared martini glass.
Double strain to remove any small blueberry pieces for a smoother drink.
Top the cocktail with a splash of lemon-lime soda and garnish with a few fresh blueberries.
Add a lemon twist for an extra decorative touch.
