Before the pig or turkey is placed in the imu,chopped pieces of banana plant are spread over the hot rocks. The white, juicy lining of this plant makes a lot of steam, but it can also cause a bitter taste, so ti leaves are layered over it. Finally, the pig or turkey is placed in the imu,along with sweet potatoes, pineapple, plantain, vegetables, and even fresh fish—all wrapped in ti leaves.
