Refreshing, tart, and fruity, this delicious summer drink is great on a hot night. And I don't need to tell you how yummy it would be with a boozy addition!
Bring water to a boil in a medium saucepan. Add the hibiscus flowers and stir well. Remove from heat, and let stand for 1 hour. Strain through a sieve, and pour into a large pitcher. Add the lemonade, stir, and refrigerate until chilled. Serve over ice, garnished with mint sprigs.
