Immerse the tea bags in 2 cups of hot (not boiling) water for 1 minute. Remove and discard the bags.
Add ice cubes to your serving glasses and pour the hot tea over it (this is an instant method if you want to drink it right away). Divide the orange juice between the glasses and add sugar to taste. Stir in a few mint leaves and serve.
If you are going to be drinking it at a later time, refrigerate until ready to serve.
