Culinary writer Rosie Lovell explores the South of France's famous Cote D'Azur and encounters a typically rustic cuisine far removed from the haughtiness of renowned French cooking - the ubiquitous (and largely unaffordable) foie gras and truffles noir!

This is a remarkable region blessed with sun, sea, mountains, flowing rivers and lush plateau - offering up the most eclectic and fantastic produce served fresh on the plate. Bon appetit!
