This one is easy, Lipton has 1 gallon bags. You put 1 bag in a medium pot of water, let it simmer but not boil for 45 minutes then pour it in a 1 gallon container. Add 1 and 3/4 cups of sugar and stir it in while its still hot. Fill the rest of the container with ice and let it sit 20 or 30 minutes before serving. It will be very good stuff.
