Wendy, IMHO, PBS is
serious and generally wonderful cooking. Food TV is just fun. Recently found that I can enjoy Emeril again so long as I keep him in small doses. Martha is indeed on everyday. Alton Brown is educational and frequently hilarious. And has anyone caught Jamie Oliver's new series, Pukka Tukka? Still pretty basic but someone washed his hair and broke him of the habit of running his fingers through his hair while cooking. I don't think any of the Food TV series would inspire a professional chef, but some are a lot of fun to watch.
BTW, some of my favorite web sites are the ones done by the folks here, such as:
The Olive Tree World a la carte
