So true how smells ( and non-visual senses in general) bring back long-forgotten memories. The smell of basil reminds me of my paternal grandmother and her beautiful hilltop house in Italy, coffee of my father, lily of the valley of my mother, and yes, whitewave, camomile fields of my birth village where I spent the first five years of my life.
Marcel Proust based his whole literary output on this involuntary memory resuscitated by our non-visual senses: taste, smell, sound. The most often quoted episode from his 'Remembrance of Things Past' is when he dipped a ^ madeleine^ into his tea and the taste brought back his early childhood, long forgotten.
