Food waste with Tom Hunt, Yotam Ottolenghi’s new book and Nigel Barden’s new TV show: listen now

This week, I find out how food waste has become central to the cooking of both eco chef Tom Hunt and Madonna favourite, Skye Gyngell. I talk to Yotam Ottolenghi about his new book Simple and meet fashion-guru-turned-Spelt-farmer, Roger Saul. And afterwards, I catch up with Nigel Barden to hear about his new TV show.
