The white, juicy lining of this plant makes a lot of steam, but it can also cause a bitter taste, so tileaves 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 tileaves. More hot rocks are spread over the bundles of food, then more tileaves, a layer of wet sacks, and a canvas covering. Dirt is shoveled in to the hole and pat down smoothly.
