My cupboard holds a basket with many random tea bags transferred out of their almost empty boxes. When the season changes to warmer weather, I begin using up these little bags by making iced tea. This afternoon, I brewed 2 green tea bags, a peppermint and a chai in 6 cups of water for about 5 minutes. (Any longer and the green tea turns bitter.)   This makes surprisingly great tasting tea  - sweetened just a bit with agave nectar.
