I think it makes it even worse in a way. Though I'd imagine Neelix to get better through the years as he starts to get to know his crew. But i do seem to remember scenes where he tries dishes from the Alpha quadrant. Though I coulda imagined that.
In "Learning Curve" he made some bluish cheese to try and make macaroni and cheese for someone. The same cheese that poisoned all the Bioneural gel packs.
And a later season 5 or 6 episode, I remember he gave half the crew heartburn with some chili.
