I was lucky enough to have great mentors both in the culinary world and in the world of chefs who became celebrities. Bobby Flay is one of my dearest friends and a tremendous mentor for me. Mario Batali is the same way. They began doing TV a little before me and they showed me the way.
If I write a character, instead of looking from the outside, like maybe a journalist would, trying to describe them physically and figuring out what kind of things they might be interested in or have in their house, I don't really do it that way. I try to feel what it would be like to be inside this person, to be them.
