PREPARATION:
- Wash chilies; remove stems and seeds. Place in 3-quart pan with water. Cover and simmer 20 minutes or until chilies are very soft. Pour chilies and liquid into blender or food processor container fitted with metal blade; process until puréed. Push purée through wire strainer; discard pulp. Add onion, garlic, oregano, salt and cumin to chili mixture.
- If using pork butt, trim excess fat. Cut meat into 1/2-inch slices, then cut into strips about 1 inch wide and 3 inches long. If using pork chops, trim fat.
- Place meat in heavy self-sealing plastic bag. Pour chili mixture over meat; seal bag. Refrigerate 1 to 2 days. Preheat oven to 325°F. Transfer meat and chili mixture to 2-1/2-quart casserole; cover. Bake 2 to 2-1/2 hours or until meat is very tender. Skim and discard fat before serving.
