I use milk or half and half or even coffeemate creamer in strong black teas. I use 1 tsp to 10 or so fluid ounces of tea or 2 tsp to a 16 oz cup. Tea waters down a lot more than coffee and when I first tried lightener in tea, I found it awful. Overpowering and like milky water. I was using way too much.
Fill the pitcher with water, adding tea leaves according to your preference (it may require more tea leaves than you think as cold water does not extract quite as much flavor as hot water). Use a good quality and strong tea such as assam for a robust flavor as more subtle types of tea will produce a weaker iced tea.
