Place blueberries, mint, and lime juice in a cocktail shaker and muddle. Add ice, vodka and honey. Shake vigorously to blend. Strain into a mason jar or old-fashioned glass. Top with seltzer water. Garnish with a lime wedge and mint sprig.
*This recipe can be doubled easily, but for the purpose of how many drinks you can make in a shaker, I kept the recipe at a two-serving size.
