Food has been widely recognised in areas such as anthropology, sociology, food science, semiotics as well as in literary, film and cultural studies. Food and eating mirror the making of a self and ...reflects a detailed and comprehensive image of our identities. As self-understanding and authentic existence are the chief objectives of any kind of philosophical inquiry, especially in postmodern times, food becomes a valuable key to that. The paper proposes to study Preethi Nair's One Hundred Shades of White as chronicle of such a journey spanning three generations of women through the metaphor of cooking. Food is one of the most popular tools in the hands of diasporic women writers to express their longing for as well as rejection and finally acceptance of their home culture. The novel is an unforgettable rendering of a mother and daughter's search for identity and 'wholeness' in an alien land and coming to terms with the 'duality' of their existence.
