There are really four celebrity chefs I really like, though the order is constantly changing.
Emeril Lagasse - Energetic, animated, and can prepare meals from the most basic to the most elegant.
Bobby Flay - Quickly rising to the top of my favorite chefs, mainly because I've taken to his preference to the Southwest flavors and barbeque. That, and being married to Stephanie March!
Paula Dean - Outside of her nasaly voice and laugh, this woman cooks the way I like! Lots of food, plenty hot, and yummy rich! Cracker Barrel Restaurant, eat your heart out!
Mario Batali - Though I oft struggle with the speed of his monologue (sp?), the guy is certainly high on the list of Italian chefs in the world. He loves to tap in to his knowledge of the history of food in Italy and the types of food available in the various regions. He certainly favors elegant presentation, which is certainly not wrong, but for a budding entrepreneur in culinary arts, maintaining an upper end style can be difficult without establishing your niche.
