During a recent trip to Turin to attend the Salone del Gusto/Terra Madre festival and Cinemambiente environmental film festival, I took some time out at the Caffe Mulassano to record an audio slideshow for Guardian Travel. Seeking gastronomic tips, I spoke to Corby Kummer, senior editor at Atlantic Monthly and author of The Pleasures of Slow Food, and Daniella Vitta, one of Turin’s genial ambassadors.
