Like other country hams, Kentucky ham is subjected to a long, dry curing process which makes it highly shelf stable and allows the ham to develop a complex and subtle flavor. Kentucky hams are rubbed with a mixture of sugar and salt, then smoked before being aged for up to one year, and they have a very dry texture, even more so than Virginia ham, another popular country ham. There are a number of ways to use the delicate, dry flavor of Kentucky ham in cooking, and a truly fine Kentucky ham can be used like prosciutto, a traditional Italian dry cured ham.
Traditional Kentucky ham starts with a Hampshire hog. Hampshire hogs were imported to the United States from England in the 1830s, because they were hardy, lean pigs which could easily forage for themselves in the woods. Hampshire hogs also grow to be very large, and they have a characteristic thin rind which led to the popular name "Thin Rind Hog." The look of a Hampshire hog is quite distinctive; the pigs have black bodies with a wide white belt which runs along their front shoulders and legs.
The animals are fed a diet of acorns, beans, clover, and grains until they reach a size which is appropriate for slaughter, and their hind legs are taken for use as Kentucky hams while other parts of the pig are cured in different ways, or sent to market as fresh meats. The legs are salted and rubbed in a spice mixture before being smoked over a hickory, apple, and corncob fire for several days. After smoking, the Kentucky ham is hung in a cool dry place to cure.
