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.
