As I sat here drinking a bottle of Lipton sweetened iced tea with lunch, I ran across a good article about Southern sweet tea at Slate.
Here in Houston, when I don’t feel like making it myself, I get my sweet tea from Chick-Fil-A, Boston Market, occasionally McDonalds, or I buy a bottle of AriZona sweet tea from the corner convenience store.
When it was open, the Grandy’s in Austin near where I lived would sell gallon jugs of their awesome sweet tea, but they closed down in 2002-2003 and that location turned into a taco joint.
