The Culinary definition for this act is called Barding. I thought I would share this article for discussion.
When meat is wrapped in strips of fat while it cooks, the practice is called barding. Barding helps to keep meat moist while it cooks, and also imparts flavor. A related practice, larding, involves inserting pure fat into a cut of meat with the assistance of special tools. Whether barding or larding, the result is a rich, flavorful cut of meat which is also moist and tender.
Bacon and fatback are two cuts of meat commonly used as barding. Fatback is exactly what it sounds like; it is a fatty cut from the back of a pig. Any meat rich in fat will work as barding, however, with darker fats like goose and duck lending a distinct flavor to the meats they are cooked with. The barding is often seasoned as well, to further flavor the meat.
The meat which is most often barded is poultry, because poultry tends to dry out during the cooking process. By wrapping the breast of a bird in bacon or fatback, the cook can ensure that the meat stays tender and moist. As the barding cooks, the fat will render out, trickling through the meat. In a sense, barding is an automatic basting system. When the meat is close to done, the barding is usually removed to allow the meat to brown.
