Did you know you can’t use food stamps at most New York City farmer’s markets? I’m guessing that’s true of a lot of places. Too bad, because there is a great new project that could make farmer’s markets even more attractive to food stamp users. The Wholesome Wave Foundation, founded by Chef Michel Nissan and Gus Schumacher, a policy guy, has launched the Double Value Coupon program, which doubles the amount of food that can be purchased with the subsidy at farmer’s markets. Only the ones that accept the stamps in the first place, of course.
