1. Place mint, blackberries and sugar in a half-gallon pitcher. Using a wooden spoon, muddle (lightly mash) the blackberries, mint and sugar until the blackberries are broken into tiny seedpods. Allow the mixture to rest 10 minutes before adding liquids.
2. Add Chick-fil-A Lemonade to the fruit mixture and set for up to four hours. Lightly stir in the club soda, and if you’re feeling extra fancy, you can rim the glasses with a combination of sugar, sea salt and lemon zest. Pour the tasty beverage over ice and top with blackberries, mint leaves and lemon slices. Enjoy!
