Add Blackberry Mojito loose-leaf tea and ¼ cup Belgian Rock Sugar into a 16 fl oz Perfectea® Maker; bring water to a boil, then pour and let steep for five minutes. When done brewing, release brewed tea over a pitcher full of ice to flash-chill, then immediately strain ice cubes. Crush remaining sugar on a flat surface. Use a lime wedge to moisten the rim of a glass tumbler, then dip rim in sugar. Muddle 10 sprigs of mint and 2 lime wedges in the glass, then add ice, rum and 6 oz of tea. Stir well and garnish with fresh sprig of mint. Cheers!
