Meanwhile, puree the watermelon in a blender or food processor. Run the puree through a strainer, pressing on the pulp to extract the juice. Discard the pulp.
Stir the watermelon juice and lime juice into the chilled tea mixture and stir well
Take serving glasses, fill almost half the glass with ice cubes ( iced tea brings out the true flavour when it is chilled, so add loads of ice cubes to your glass before serving ), then pour the watermelon tea.
Garnish with a piece of watermelon and enjoy the chilled refreshing watermelon iced tea.
