Singer Mel B joins Jamie Oliver and Jimmy Doherty for some Caribbean cooking. Together they recreate curry chicken, rice and peas, and Mel discovers just how much love went into her Grandma Iris' recipe back on the island of Nevis. Away from the pier, the boys become cowboys for the day, putting in a shift farming British buffalo to make mozzarella. Jamie puts a spin on the traditional Friday night takeaway with a mushroom shawarma that packs a tasty punch, while Jimmy cooks some bay-salt prawns and sweet chilli sauce for an impressive party piece.
