Prep: Cut the bottom part of the stem form each leaf.
Parboil: Bring a large pot of water to a simmer. Nearby, arrange a large bowl of ice water. Working in batches, drop a leaf in the hot water for 20 to 30 seconds, or until the leaf is soft and pliable. Immediately plunge it into the ice water to stop the cooking process, then place on a clean towel.
Assemble: Place desired fillings in a oval mound near the center of the leaf. Fold the sides of the leaf on top of the mound, then tightly roll from the stem to the top of the leaf. Serve immediately.
