I enjoy watching Mario Batali, Emril, Bobby Flay (although he can be real arrogant at times–but he knows what he is doing) Alton Brown (the best show out of the bunch of new shows that they produced at the time) Jacques Pepin, Charlie Trotter,
Wolfgang Puck, Ming Tsai, Lydia Bastianich (I call her my Italian grandmother I wish I had, ha!) I also enjoyed watching reruns of The Galloping Gourmet.
There's probably some that I'm missing, but that's what comes to mind at the moment.
I'll spare you my thoughts on Rachel Ray. On one hand, if she is helping in some way, get better meals on the table at dinner time...then great, I'll leave it at that.
