Preparation:
Bring 4 cups of water to a boil. Remove from heat and add 4 bags of mint tea. Allow to steep for 10 minutes. Discard tea bags and pour tea into a small pitcher. Refrigerate for at least 3 hours or until well chilled. Chill tall glasses in fridge or shortly in freezer, if desired. Add crushed ice, 1 cup of tea, sweetener, if desired, and 1 or 2 teaspoons lime juice, depending on how tart you like your tea. Stir. Add 1/2 cup sparkling water. Squeeze mint sprig and add to glass. Garnish with half a lime slice, if desired. Serves 4.
