Well, as far as TV personalities go:
I grew up with Julia Child and with mom, cooked many of the French classics as best as we could in the limitations our home kitchen.
Currently I like to watch Tyler Florence, Mario Batali, Tony Bordain when he's cooking or "teaching" not just being snide, Sara Moulton.
I have had some great chefs as teachers at CIA. The passion, knowledge, and skill of these chefs is inspiring.
My favorite local chef is Nick Garyantes of Restaurant 821 in Wilmington DE ... very creative ... another local of national renown is David Leo Banks of Harry's Savoy and Seafood Grill.
