I saw this noted on EYB the other day and finally got around to listening to the first two episodes of Yotam Ottolenghi's podcast, Simple Pleasures.
The premise is that a different guest visits him to chat and eat a meal. The first guest was Nadiya Hussain, who won the Great British Bake Off a few seasons back and the second episode features Nigella Lawson.
Not sure if this will just be a limited run to flog his new book, Simple - his website has a link to a recipe from the book for each episode - or if it will continue.
The slow-cooked chicken with a crisp corn crust from the Nigella Lawson episode sounds awfully good!
