I like to prepare large batches of this tea for ease of use (especially during the winter). In order to do so, I make a very concentrated infusion by adding 5-6 tablespoons of tea blend to one quart of water that has been brought just to a boil. Allow tea to steep for 5 minutes. Strain (composting plant material). Refrigerate the concentrate in a glass mason jar. When ready to serve, mix one part concentrate with three parts water. Reheat to serve hot or serve cold over ice.
