Ham is a processed meat made from the hind leg of a pig.

It is created through various preservation methods known as curing. This process can involve salt, liquids, or smoke to change the meat. Because of these methods, ham is considered a compound foodstuff. It consists of the original meat plus the remnants of preserving agents like salt. People enjoy ham in many forms, from whole cuts to mechanically formed pieces. It is a global food with many regional specialties.

There are two primary methods for producing ham: dry curing and wet curing. Dry curing, or salting, involves cleaning raw meat and covering it in salt.

This process uses pressure to squeeze fluid out of the meat. Workers may also add specific herbs and spices for flavor. The hams are washed and hung in dark, temperature-regulated spaces. They must air-dry for a specific amount of time. This duration varies greatly depending on the specific type of ham being made. For example, Jinhua ham takes 8 to 10 months to complete. Jamón serrano requires 9 to 12 months of curing. Prosciutto di Parma takes more than 12 months. Iberian ham can take up to 2 years to reach its desired flavor.

Modern dry-cured hams often use nitrites, such as sodium nitrite or potassium nitrite. These chemicals prevent bacterial growth and react with myoglobin in the meat. This reaction gives the ham a desirable dark red color. The ratio of salt and nitrites affects how much the meat shrinks. However, nitrites must be carefully regulated because they can be toxic. During cooking, nitrites can react with amino acids to form nitrosamines. These are substances known to be carcinogens. Dry curing also triggers enzymatic reactions within the meat. Enzymes like cathepsins and calpains cause proteolysis, which breaks down muscle tissue. This process creates small peptides and free amino acids. Meanwhile, adipose tissue undergoes lipolysis to create free fatty acids.

Wet curing is a different method called brining. This involves immersing the meat in a liquid brine. Sometimes, ingredients like sugar are added to the brine for flavor. The meat typically stays in the liquid for 3 to 14 days. This process can also be done by pumping the solution into the meat. Pumping is often quicker than immersion. It also ensures a more even distribution of salt throughout the meat. Wet curing can increase the final weight of the product by about 4%. Most wet-cured hams, such as Prosciutto Cotto, are cooked. Italian regulations for this ham allow for many ingredients. These include salt, nitrites, sugar, and various proteins or starches.

Smoking is an additional preservation technique used for ham. The meat is placed in a smokehouse to be cured by smoke. This process creates specific flavor compounds like guaiacol. These compounds come from the combustion of lignin in the wood. Lignin is a major part of the wood used in the smokehouse.

Smoking adds a distinct layer of complexity to the ham's taste and aroma.

Laws exist to ensure that ham is labeled accurately. In the United States, the term "ham" refers only to the hind legs of swine. If a label says "smoked," the meat must have been hung over wood chips. If it says "hickory-smoked," it must use only hickory wood. Simply adding "smoke flavor" is not enough to call it smoked. Such products must be labeled "smoke flavor added." Other rules exist for terms like "honey-cured" or "lean." For instance, "honey-cured" must contain at least 3% honey. Many hams also have protected designations to safeguard their history. These include Prosciutto di Parma from Italy and Jamón Ibérico from Spain.

Ham is a versatile ingredient used in many different ways. It is often sliced for sandwiches, such as a ham and cheese sandwich. It is also a common topping for pizza in the United States. In the United Kingdom, a cured pork leg that needs more cooking is called gammon. Gammons can be served as steaks that are fried or grilled. Many cultures enjoy cooked ham joints during Christmas celebrations. While ham is a popular food, it is a type of processed red meat. The International Agency for Research on Cancer notes that processed meat can cause cancer. It is also linked to higher risks of cardiovascular disease and type 2 diabetes.
