Place your coupe glass in the freezer to chill.
In a cocktail combine 2 ounces of vodka, ½ ounce of triple sec, 1 ounce of lemon juice, and 1 ounce of blueberry syrup.
Add ice to the shake and shake vigorously for 15-20 seconds until well chilled.
Remove the coupe glass from the freezer and strain the cocktail into the chilled glass.
Add a lemon twist for garnish.
