I suppose it's a stew if you make it that thick. I've see stuff called gumbo that you could serve on a plate and eat with a fork. No bowl needed. I prefer a thickened liquid. I use file to thicken mine but it's still more of a soup than a stew.
Dude - you couldn't pay me to use a jar roux and my gumbo would probably beat yours any day. One thing I am known for in this town is my ability to cook. So you might want to not talk out of your ass next time.
Steve, what's your opinion on roux in a jar? I've used both and can't tell a difference. They're both pretty much flour & water correct?
