According to Ed's teacher, one of London's top chefs, to succeed as a chef you must have a passion for food, the ability to run a team, confidence, work to very precise times, and be able to cook.
So, could Ed cook? He explained his technique was to "wait until the burger went brown on both sides; he didn't have to do much more. To test his skills, his teacher asked him to cook the food in his fridge, telling Ed he could prepare it any way he wanted. The results were not good. Even the vegetables were overcooked, as Ed didn't realize that , he didn't need to boil carrots for an hour or more.
