Make Blueberry Syrup (if making at home):

Combine 1/2 cup of blueberries, 1/2 cup of sugar, and 1/2 cup of water in a small saucepan.

Bring to a simmer and cook until the sugar has dissolved and the blueberries are soft.

Strain the mixture to remove the blueberry skins and let it cool.

Prepare the Cocktail:

In a shaker, combine the vodka, fresh lemon juice, and blueberry syrup.

Add ice cubes to fill the shaker halfway.

Shake well until the outside of the shaker feels cold.

Serve:

Strain the mixture into a chilled glass filled with fresh ice.

Garnish with fresh blueberries and a lemon slice or twist.

Optional: For a bit of sparkle, top off the cocktail with a splash of club soda.
