To fill and wrap the leaves with the humitas mixture, use 2 leaves of good size for each humita. Put the leaves one on top of the other and fill the leaves with a good amount of the corn mixture. Next, fold the sides of the leaves in and the tip over. Then use the strips of the small leaves to tie the humita closed. Put the stuffed and wrapped leaves in the pot with the steamer, placing each humita on a diagonal, with the open part facing up. Cover the humitas with the remaining leaves and cover the pot tightly.
