Umami is the Japanese word for their observation of a 5th taste (the others are salty, sweet, sour, bitter). It refers to foods with a high concentration of certain glutamates. There are a number of those foods in this burger, Cervena is the perfect conduit to bring them together in harmony.
This is a quick and easy dish that can be served as an appetizer or main course. It fits well with the Palio diet, and is great a low fat dish as well.
