For a half-gallon of tea, brew 2 family-sized (or 6 regular) black tea bags in 16 oz of boiling water. I use Luzianne decaffeinated black tea.) Add a few sprigs if fresh lavender and a few sprigs of fresh lemon balm. Brew together for a total of 30 minutes or more. Pour over ice into pitcher. Add a fresh sliced lemon. Delish!
