In The Worldly Traybake, Rukmini Iyer takes us on a culinary journey. She collects the tastiest and most surprising oven dishes from around the world. In Africa, we enjoy piri-piri prawns with sweet potato, in the United States we indulge in rocky road brownies, and in Asia, we eat Indian chicken tandoori with mint. In the Middle East, we put a Persian herb frittata in the oven and finish in European style with a savory pie.
