The recipe for sun tea on MarthaStewart.com permits use of any tea brand, while a recipe at RecipeCurio.com specifies Lipton tea. A typical sun tea recipe requires the steeping of loose tea or tea bags in water under the sun for a few hours.
The recipe on RecipeCurio.com reproduces an old newspaper clipping and suggests placing three family-sized Lipton tea bags or nine regular Lipton tea bags with cold water in a gallon jar before loosely putting the lid on and allowing the mixture to warm under the heat of the sun. After three to four hours, remove the tea bags and serve the tea with any desired ingredients such as ice, lemon or sweeteners. Keep the tea in the refrigerator within five hours from the commencement of the time of brewing.
