What I enjoy about his show and his personality is that he approaches food the way most of us who enjoy cooking and eating but aren't trained chefs do, with honesty, directness and a need for simplicity so not to overwhelm the cook with recipes that require degrees in food preparation. Mark, maybe I should call him Mr. Bittman, a food column writer for the New York Times also has a video column on their website.
In each 3-5 minute segment in his down to earth way he prepares a recipe that is simple, elegant and makes the mouth water. Watching makes me want to set aside the time to make myself a quick and wonderful meal to enjoy in the silence left by not having a TV.
PS - There's even a blogspot.com blog that honor's Mark Bittman http://mycrushonmarkbittman.blogspot.com/ (I might have to become a follower!)
