Food is inherently nostalgic. We all have memories of dishes that our family cooked or that we ordered at our favorite restaurants growing up, and we are constantly creating new food memories. These memories can be activated by sight or smell, and of course, taste. A slice of our favorite pizza or a meal at a hot new restaurant can cause a euphoric reaction in people, similar to what one feels when watching sports, listening to music or seeing a great film or Broadway production. They all evoke passion.
