I think I must have missed his heyday, but my local PBS channel ran a few of his reruns, and I don't know what the heck to think.
He started off the show with this heavy cajun accent, and then all of a sudden, he was completely accent-less, midwestern as I am...and then he moved on to another topic, and he had the accent again, but not as hokey as at the beginnin' of the show.
It was all rather odd and made me skeptical as to whether his recipes would be authentic or as contrived as the accent.
Other than the show, I've seen his face on some seasonings, but that's about it.
So, was he a TV fabrication? Or is he someone I should know more about?
