The problem is that there is no real definition since all food comes from some place at some time. Even ingredients that are used in many Indian dishes today like Chili peppers and tomatoes are from the new world, so could not have been considered "authentic" at some time int he past. Basically "authentic" when it comes to food feels more like a kind of nostalgia.
