A refreshingly tart-and-sweet vodka lemonade swirled with a quick homemade blueberry syrup. Bright, juicy, and perfect for warm afternoons or easy entertaining.
Make the blueberry syrup: In a small saucepan, combine blueberries, sugar, and 0.5 cup water. Bring to a gentle simmer over medium heat, mash berries with a spoon, and cook until the sugar dissolves and the berries release their color, about 5 minutes.
Strain the syrup through a fine-mesh sieve into a bowl or measuring cup, pressing on solids. Discard solids and let the syrup cool slightly.
Mix the lemonade: In a large pitcher, combine lemon juice, 3 cups cold water, vodka, and all of the blueberry syrup. Stir until evenly mixed. Taste and adjust with more water for a lighter sip or more lemon for extra tartness.
Serve: Fill glasses with ice, pour the spiked blueberry lemonade, and garnish with lemon slices, extra blueberries, and mint sprigs.
Notes
For a bubbly twist, swap some of the cold water for club soda just before serving. Make it ahead by preparing the blueberry syrup up to 3 days in advance and chilling it. For a mocktail version, omit the vodka and add an extra 1.5 cups cold water.
