You couldn't get any more authentic. This was taught to me by my Cajun maternal grandmother who was taught by her maternal grandmother. I've never run across a gumbo recipe with "parsley meatballs". These are optional. I asked my mom about this and she said that this was probably used to "extend" the gumbo because there were usually so many mouths to feed. It's a great addition and worthy of the effort. An observation: never have I eaten Gumbo until recently that has been deboned and this was always at restaurants. Oh, using a baking hen results in a more velvety texture and I have to honestly say that I've never used a fryer. One last thing...it's freezable.
