Pork

The tried-but-true saying that everything but the pig's squeal can be used is accurate indeed. Though pigs are bred primarily for their meat (commonly referred to as pork) and fat, the trimmings and lesser cuts (feet, jowl, tail, etc.) are used for sausage, the bristles for brushes, the hair for furniture and the skin for leather. The majority of pork in the marketplace today is cured — like bacon and ham — while the remainder is termed "fresh."

Grading

Slaughterhouses can (but usually don't) request and pay for their pork to be graded by the U.S. Department of Agriculture (USDA). The grades are USDA 1, 2, 3, 4 and utility — from the best downwards — based on the proportion of lean to fat. Whether graded or not, all pork used for intrastate commerce is subjected to state or federal inspection for wholesomeness, insuring that the slaughter and processing of the animal was done under sanitary conditions. Pork shipped interstate must be federally inspected. Today's pork is leaner (about 1/3 fewer calories) and higher in protein than that consumed just 10 years ago.

Cooking

Thanks to improved feeding techniques, trichinosis in pork is now also rarely an issue. Normal precautions should still be taken, however, such as washing anything (hands, knives, cutting boards, etc.) that comes in contact with raw pork and never tasting uncooked pork. Cooking it to an internal temperature of 137°F will kill any trichinae. However, allowing for a safety margin for thermometer inaccuracy, most experts recommend an internal temperature of from 150° to 165°F, which will still produce a juicy, tender result. The 170° to 185°F temperature recommended in many cookbooks produces overcooked meat. Though pork generally refers to young swine under a year old, most pork today is slaughtered at between 6 to 9 months, producing a leaner, more tender meat. Though available year-round, fresh pork is more plentiful (and the prices lower) from October to February. Look for pork that is pale pink with a small amount of marbling and white (not yellow) fat. The darker pink the flesh, the older the animal.

Storgage

Fresh pork that will be used within 6 hours of purchase may be refrigerated in its store packaging. Otherwise, remove the packaging and store loosely wrapped with waxed paper in the coldest part of the refrigerator for up to 2 days. Wrapped airtight, pork can be frozen from 3 to 6 months, with the larger cuts having longer storage capabilities than chops or ground meat.

Lamb

Lamb is a sheep less than 1 year old, known for its tender meat. Baby lamb and spring lamb are both milk fed. Baby lamb is customarily slaughtered at between 6 and 8 weeks old. Spring lamb is usually 3 to 5 months old; regular lamb is slaughtered under a year of age. Lamb between 12 and 24 months is called yearling; when over 2 years, it's referred to as mutton and has a much stronger flavor and less tender flesh.

Grading

There are five USDA grades for lamb based on proportion of fat to lean. Beginning with the best, they are Prime, Choice, Good, Utility  and Cull . When purchasing lamb, let color be the guide. In general, the darker the color, the older the animal. Baby lamb will be pale pink, while regular lamb is pinkish-red. Lamb can be purchased ground and in steaks, chops and roasts. Lamb variety meats can also be purchased.

Storage

Refrigerate ground and small lamb cuts loosely wrapped for up to 3 days. Roasts can be stored up to 5 days. Ground lamb can be freezer-wrapped and frozen up to 3 months, solid cuts up to 6 months.
