That's what I mean. The chefs in the US concentrate more on professional technique and they are more down to earth....and HUMBLE. They understand that entertaining the audience is important while cooking, BUT they tend to do it in a natural way (except for Emeril, and Rachel Ray in my opinion) and don't act over the top.
Maybe deep down Rahat is really insecure and that's why she feels the need to constantly remind the viewers that she is the most professional cook, and that you can learn cooking best from nobody but her. When you are a celebrity (movie star, sports player, politician, even a chef), you need to have self-confidence because you are constantly being scrutinized by the public and you can't always let their judgments break you down. BUT with rahat, the self-confidence is OVERDONE. And it ends up turning people off.
