Andrew and Giorgio travel from the tip of the heel up Italy's dramatic east coast. Their journey starts in the instep of Italy and the region of Basilicata. Its most famous town is the spectacular Matera, also known as Sassi or 'Stones' after its caves inhabited since Palaeolithic times, and a Unesco world heritage site. There, Giorgio cooks a peasant recipe of mutton 'pignata' in a restored cave.
