I watch a lot of food shows on PBS, food network, etc. and they make a lot of the fact that a chef's goal in offering creative dishes should be those that contain a sweet, sour, hot and salty component. A new one has been added by the Japanese called "umami" which is a savory component. What dish do you think is a good example of "sweet, sour, salty and hot? And what dishes are an example of "umami"?
