Sun Brewed Iced Tea is one of the simpliest things to make. I just use a giant jar, throw in some tea bags (I like Orange Pekoe) and let it sit in the sun for a day or so. Then I move it to the fridge - leave the tea bags in - and let it hang out until I want to drink it. When ready to drink, I pour it in a glass, add some lemon juice, and usually some ice. And that's it. I used to add some simple sugar to sweeten it but tried it without and it's pretty yummy by itself.
Sun Brewed Iced Tea = summer!
