Did you know it was possible to cook with the steam from a volcano? David returns to his roots and visits Pozzuoli, a small town just outside Naples where his father was born. There he meets Marianna Vitale, a Michelin Star chef who takes David on a cultural food tour including a visit to the Solfatara Volcano, an active crater, where they cook seafood to perfection in this unconventional way. David spends the rest of his trip catching octopus with the locals and then cooks it up for his relatives.
