All of the people you mentioned have a passion for food, cooking, teaching. Plus, Julia, Justin, Emeril and Gordon all seem to have big personalities.
As for me, personally, it is Alton. I know AB isn't a chef (he doesn't call himself one nor is he by classic definition) but he has those same passions for teaching, cooking and food. That passion to do better in teaching and curiosity is what helped him create his show and he does I great job getting that across in the show and his books.
I like all of the chefs you mentioned, btw, but AB is just the one I've learned so much from in food science and techniques that he's my favorite.
Looking forward to the blog post
