Sabrina Ghayour makes sticky harissa lamb buns with a punchy cucumber pickle, while Richard Bainbridge serves up a confit tomato tart with a nut-free pesto. Nadiya Hussain transforms the flavours of samosas into a keema plate pie served with a refreshing charred mango salad, before Gennaro Contaldo stirs up chaos with his lemon and ricotta mezzaluna. And Sue Perkins faces her food heaven, a Thai-inspired seafood supper with mussels, cuttlefish and brill, or her food hell, Turkish eggs with whipped goats' cheese. Meanwhile, Rick Stein learns all about botanicals before having a tipple or two, Dame Mary Berry gets her hand dirty as she gardens with AJ Odudo, and the Hairy Bikers enjoy a picnic on the picturesque Isle of Bute.
