This week on Why We Cook Chef Smarty Pants laments America's obsession with soda, and fears for a close friend with a diet soda addiction. When a search for a soda with maximum flavor and minimum sweetness ends without a clear winner, she ponders the potential for creating her own soda replacement beverage. By taking stock of some of the most soda-worthy fruits from around the world (heavily favoring the citrusy, sour, tart fare), Chef Erica is able to recommend some potential concoctions that might satiate even the hardest soda devotee.
