I admit it, I am a Food Network junkie. Chopped and Iron Chef are my favorite shows. Although they're just like 'sports for food' and not very vegetarian friendly; for some reason I enjoy watching them. I think it's because I believe that I'll learn by osmosis or something.
One show that really annoys me is that Alton Brown show. BUT I did come across an episode that was extremely enlightening and helpful. It's great especially for someone like me who loves to cook, but was never formally trained... I learned by watching my Mom. No offense mom, but even you didn't show me these tips and tricks. Watch and learn.
