On the edge of Lake Geneva, in the town of Vevey, a gigantic steel fork rises out of the water, like a shining emblem of the power and pleasure of food. It&rsquos an apt signature landmark for a town that prides itself on its gastronomic history. Vevey was the place where one of those great life-enhancing inventions &mdash the milk chocolate &mdash was first created, in 1875. It is also the birthplace of such universally loved comfort foods as Ovaltine, Maggi and Nescafé, invented by Nestlé, the world&rsquos largest food company which has its headquarters here (the giant fork sculpture in the lake is also courtesy Nestlé). But I am steered away from all things processed and packaged during my food safari in Vevey and its neighbourhood in the Lake Geneva region. Instead, I am offered a non-stop feast of the freshest harvest of fields, forests and lake &mdash so exquisitely presented, they look like still-life masterpieces transferred from canvas to plate.
