These are fragrant parcels of succulent meat seasoned with mildly sweet Guajillo Chiles. Everyone swoons over these. Cook's Note: meat can be marinated, in bowl or enclosed in banana-leaf packages, up to 24 hours. Meat is best eaten from freshly baked banana-leaf packages, but left overs will keep for 3 days. Reheat, wrapped in foil, in a 350°F oven, 20 to 30 minutes. From Gourmet magazine Sept. 2007.
