User Experience from Product Creation Perspective

Virpi Roto (Sr. Research Scientist Mobile HCI at Nokia) stated in this paper  that "(...) we can talk about user experience whenever there is interaction with a product. A cake does provide user experience, because I can interact with it: I touch the cake and feel how soft it is, and bitting that cake gives delicious taste as 'feedback'. That's how I interact with the cake." - So, food and UX do have things in common.
