Gino heads South along the Adriatic to visit two UNESCO sites. First the beautiful town of Ravenna - famed for its byzantine mosaics - where Gino meets the artists who restore these ancient works, and has a chance to put his mark on a new mosaic.... (more) Outside the oldest restaurant in the city he makes a classic Piadina flatbread - explaining how to make the very best homemade pesto. Gino then heads South and onto somewhere he has never been before - the Republic of San Marino - clinging to the top of a mountain it is the oldest and fifth smallest nation in the world. After meeting the crossbowmen and with incredible views of the coastal plains below, he cooks up a delicious panettone and honey pudding fit for a queen.
