While there are a lot of authentic qualities about this gumbo, no, I would not state that it is authentic for a few different reasons. First, at the heart of the dish, it is a meat based dish. So you won't find mushrooms or plant-based sausage in the original. Second, gumbos are so different based on the region where you are from and most recipes are passed down from family to family. So I honestly don't know if there is just one u0022authenticu0022 gumbo recipe out there.
