No need to. Hellmann's have the market.
Back to Rush's iced tea. The first time I had it brought back a memory long lost. My bff's mother used to make sun brewed iced tea. I remember the glass pitcher, sitting on the table in the backyard. It had little yellow suns circling the pitcher.
The first time I tried his iced tea, that memory came crashing down on me. It was my favorite as a youngster. Her mom ALWAYS had food in the house as well, so you know that's where we'd all wind up for lunchtime!
I don't have many fond memories of my childhood, but that was one of them.
Why don't you make your own? There are hundreds of teas out there that are a LOT cheaper than Rush's. I refuse to buy something I can make for one tenth the price.
