Steep 4 or 5 black tea bags, 2 cups turbinado sugar and 2 handfuls of fresh mint in 3 cups simmering water for 5 minutes, stirring to dissolve the sugar. Strain into a pitcher; add the juice of 3 limes, 1 1/2 cups light rum, 1 cup cold water and another handful of mint. Stir vigorously, crushing the mint with a wooden spoon; chill. Serve over ice with lime and more mint.
