Blueberry Moscow Mule

Combine blueberries, sugar, water, and salt in a pot over medium heat; bring to a boil. Reduce heat and simmer until desired thickness is achieved, 3 to 5 minutes. Remove from the heat and set aside to cool, about 10 minutes.

Combine vodka and lime juice, stir, and pour into a copper mug or mason jar. Add ice cubes. Pour ginger beer over ice, then top with 3 tablespoons blueberry syrup. Stir to combine and garnish with lime wedge.
