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.

Add blueberries, sugar, and water to a small saucepan.

Bring to a medium heat and stir until the sugar is dissolved.

Simmer for about 10 minutes until the blueberries start to break down.

Pour the mixture through a fine mesh strainer to remove the solid blueberry pieces.

Let the syrup cool and transfer it to an airtight container. It can be stored in the refrigerator for up to two weeks.
