Hams may be fresh, cured, or cured-and-smoked. The usual color for cured ham is deep rose or pink; fresh ham (which is not cured) has the pale pink or beige color of a fresh pork roast; country hams and prosciutto (which are dry cured) range from pink to mahogany color.
Hams are either ready-to-eat or not. Ready-to-eat hams include prosciutto and fully cooked hams; they can be eaten right out of the package. Fresh hams and hams that are only trichina treated must be cooked by the consumer before eating; in most countries, these hams will bear a safe handling label.
Curing is the addition of salt, sodium nitrate (or saltpeter), nitrites and sometimes sugars, seasonings, phosphates and ascorbates to pork for preservation, color development and flavor enhancement.
Nitrate and nitrites contribute to the characteristic cured flavor and reddish-pink color of cured pork. Nitrite and salt inhibit the outgrowth of Clostridium botulinum, a deadly microorganism which can occur in foods. The nitrates and nitrites create cancer-causing chemicals when overcooked, so avoid eating ham that has been browned or blackened.
The two most-used methods of adding solutions to pork are: injection into muscle by needle; and tumbling or massaging into muscle to produce a more tender product.
Dry curing edit
In dry curing, the process used to make country hams and prosciutto, fresh meat is rubbed with a dry-cure mixture of salt and other ingredients. Dry curing produces a salty product. In 1992, FSIS approved a trichina treatment method that permits substituting up to half of the sodium chloride with potassium chloride to result in lower sodium levels. Since dry curing draws out moisture, it reduces ham weight by at least 18% -- usually 20 to 25%; this results in a more concentrated ham flavor.
Dry-cured hams may be aged from a few weeks to more than a year. Six months is the traditional process but may be shortened according to aging temperature.
These uncooked hams are safe stored at room temperature because they contain so little water, bacteria can't multiply in them. Country hams may not be injected with curing solutions or placed in curing solutions but they may be smoked.
Wet curing or brine cure edit
Brine curing is the most popular way of producing hams. Contrary to popular misconception, not all brine-cured hams are "injected". Many traditional ham styles (such as the English Wiltshire ham) are wet-cured hams. Brining ingredients can be salt, sugar, sodium nitrite, sodium nitrate, sodium erythorbate, sodium phosphate, potassium chloride, water and flavorings. Smoke flavoring (liquid smoke) may also be injected with brine solution. Cooking may occur during this process.
Smoking and smoke flavoring edit
After curing, some hams are smoked. Smoking is a process by which ham is hung in a smokehouse and allowed to absorb smoke from smoldering fires. This gives added flavor and color to meat and slows the development of rancidity.
How much to buy edit
When buying a ham, estimate the size needed according to the number of servings the type of ham should yield:
- 1/4 - 1/3 lb. per serving of boneless ham
- 1/3 - 1/2 lb. of meat per serving of ham with little bone
- 3/4 - 1 lb. of meat per serving of ham with large bone.
Ham glossary edit
Labeling regulations referenced in this glossary are those of the United States.
- Bayonne Ham, Air dried ham from the Adour valley in S W France 'the Basque country'. Salted, then air cured for a mimimum of seven months.
- Butt (sirloin) end, half, or portion - the upper, meatier part of the whole leg; a butt portion has had some center slices removed for separate sale as ham steaks or center cut ham slices. The half includes this meat.
- Canned ham -- Canned hams come in two forms:
- Shelf stable - store on shelf up to 2 years at room temperature. Generally not over 3 pounds in size. Processed to kill all spoilage bacteria and pathogenic organisms such as Clostridium botulinum, Salmonella and Trichinella spiralis. The product is free of microorganisms capable of growing at ordinary room temperature. However, high temperature storage -- above 122° F (50° C) -- may result in harmless thermophylic bacteria multiplying and swelling or souring the product.
- Refrigerated - may be stored in refrigerator up to 6 to 9 months. Its weight can be up to 8% more than original uncured weight due to uptake of water during curing. It need not be labeled "Added water" except for "In Natural Juices." Net Weight is the weight of the actual ham excluding the container. Processed at a time/temperature sufficient to kill infectious organisms (including Trichinae) but the ham is not sterilized so spoilage bacteria may grow eventually.
- Capacolla - Boneless pork shoulder butts which are dry cured; not necessarily cooked., Ham capacolla is made with ham instead of pork shoulder butts.
- Cook before eating - needs further cooking. Is not completely cooked in the plant and should be cooked to 135° F.
- Cottage ham - a ham made from the shoulder butt end.
- Country ham - uncooked, cured, dried, smoked-or-unsmoked meat products made from a single piece of meat from the hind leg of a hog or from a single piece of meat from a pork shoulder. Smithfield and country hams are not fully cooked but are dry cured to be safe stored at room temperature. They should be cooked before eating according to manufacturer's instructions. A ham labeled "Smithfield Ham" must be processed in the city of Smithfield, Virginia.
- Fresh ham - the uncured leg of pork. Since the meat is not cured or smoked, it has the flavor of a fresh pork loin roast or pork chops. Its raw color is pinkish red and after cooking, greyish white.
- Fully cooked - needs no further cooking. Fully cooked in plant. Can be eaten directly as it comes from its packaging or reheated.
- Gelatin - about one-fourth ounce of dry gelatin is often added before a canned ham is sealed to cushion the ham during shipment. During processing, natural juices cook out of the ham and combine with the gelatin. When the ham cools, a jell forms. Gelatin is included in the net weight statement on the label.
- Ham - the product is at least 20.5% protein in lean portion and contains no added water.
- Ham with natural juices - the product is at least 18.5% protein. Can weigh 8% more than uncured weight. Example: canned hams.
- Ham -- Water added - the product is at least 17.0% protein with 10% added solution; it can weigh 8% more after curing than uncured.
- Ham and water products - Product may contain any amount of water but label must indicate percent of "added ingredients." For example, "X % of weight is added ingredients" for any canned ham with less than 17.0% protein.
- Ham steak - another name for center cut ham slices.
- Hickory-smoked ham - a cured ham which has been smoked by hanging over burning hickory wood chips in a smokehouse. May not be labeled "hickory smoked" unless hickory wood has been used.
- Honey-cured - may be shown on the labeling of a cured product if honey is the only sweetening ingredient or is at least half the sweetening ingredients used, and if the honey is used in an amount sufficient to flavor and/or affect the appearance of the finished product.
- "Lean" ham - The term "lean" may be used on a ham's label provided the product contains less than 10 grams fat, 4.5 grams or less of saturated fat, and less than 95 milligrams cholesterol per 100 grams and Reference Amount Customarily Consumed (RACC).
- "Extra lean" ham - A ham labeled "extra lean" must contain less than 5 grams fat, less than 2 grams saturated fat and the same cholesterol as allowed per the amount of "lean" ham.
- Picnic, pork shoulder picnic - a front shoulder cut of pork which has been cured in the same manner as ham.
- Prosciutto ham - An Italian-style dry cured raw ham; not smoked; often coated with pepper. Proscuitti can be eaten raw because of the way they are processed. Parma ham is prosciutto from the Parma locale in Italy. These hams tend to be larger than the U.S. produced product, as Italian hogs are larger at slaughter.
- Sectioned and formed or Chunked and formed - a boneless ham that is made from different cuts, tumbled or massaged and reassembled into a casing or mold and fully cooked. During this process it is usually thoroughly defatted.
- Shank end, half, or portion - the lower, slightly pointed part of the leg. A "portion" has the center slices removed for separate sale as "ham steaks" or center cut ham slices. The half includes this meat.
- Skinless, shankless - A ham with all of the skin and the shank removed. The leg bone and aitch (hip) bone remain.
- Sugar cured - a term that may appear on ham labels if cane or beet sugar is at least half the sweetening ingredients used and if the sugar is used in an amount sufficient to flavor and/or affect the appearance of the finished product. Most hams contain sugar in the curing mixture.
- Westphalian ham - A German-style dry cured ham that is similar to Prosciutto; smoked, sometimes with juniper berries. Also called Westfalischer Schinken.
