I recommend drinking iced tea all the time because it is delicious. My recipie is as follows:

2 bags of green tea
2 bags of earl grey tea
1 bag of a floral tea

Boil 1-1.5 cups of water and let the tea steep in that water. Then add 3-4 cups of cold water and ice and it’s ready to drink.

You can use whatever brand of tea you wish, but I use bigelow for the green and earl grey, and something from b&n for the floral tea.
