Joanna Lumley, Pastry Snake & Curry

Jamie Oliver and Jimmy Doherty are joined by Joanna Lumley in their cafe at the end of Southend Pier. This time the menu's exclusively vegetarian, as Joanna cooks the King of Malaysia's favourite dish, bringing back to life the tastes and smells of her childhood. Jamie prepares a spectacular M'hanncha - a spiral of filo pastry stuffed with pearl barley and butternut squash. The boys take to the road to champion British fava beans - which could help both our farmers and our diet. And Jimmy gets green fingered, creating a vertical veg patch for a 10th-floor city balcony - proving you can grow your own veg no matter where you live.
