Chamorro PibilChef Joaquim Ocampo Castillo shared this very special recipe. He's a native of Yucatán, and is now with Casa Vieja restaurant in Tlaquepaque, a suburb of Guadalahara. Fresh pork shank is seasoned with Yucatán spices, wrapped in banana leaves and steam-baked until very tender. Fresh pork shank, also called fresh pork hock (but not ham hock, which is smoked, not fresh), may need to be special ordered. If unavailable, use lamb shank instead.Banana leaves, usually frozen in one-pound packages, can be found in Mexican and Asian markets. The leaves are about 30 to 40 inches long, and are cut to the size needed to wrap the meat. Achiote seasoning paste is found in Mexican markets. Serve with black beans and fresh salsa.
