I have had a 1 qt. heavy glass pitcher for many years.  It has been used mainly for mixing and storing powdered milk.  I also have several boxes of herbal tea in the pantry that I normally drink hot.  I decided that I would dust off the pitcher, and make a batch of sun tea, as a healthier alternative to diet Coke.  I use 4 tea bags, fill the pitcher with cold water, and set it out in the sun for about an hour or so.  I'm using the "assortment" boxes so I can try a different flavor each time.  Most don't even need a sweetener.  I just chill and pour over ice.    My favorite so far is Tangerine Orange Zinger.  An added bonus is the the used tea bags can go in the compost bin!
