The Meat Buyers Guide: Meat, Lamb, Veal, Pork and Poultry by NAMI (North American Meat Institute) 8th Edition
Edited by NAMI (formerly NAMP), this is the definitive reference on all the different cuts of meat, with charts, excellent photos, a glossary, and nutritional info. It is aimed at butchers, chefs, and ranchers, but a home chef can learn a lot.
A quote: “Spareribs shall consist of at least 11 ribs and associated coastal cartilages and may include portions of the sternum and diaphragm. The membranous portion of the diaphragm, close to the lean, and any portion of the diaphragm not firmly attached close to the inside surface of the ribs, shall be excluded. The lean shall not extend more than 2.0 inches (5.0 cm) past the curvature of the last rib and coastal cartilage. Heart fat on the inside surface of the ribs shall not exceed 0.25 inch (6 mm) average depth. Leaf fat shall be trimmed practically free from the diaphragm and transverse abdominis.” OK. So it’s a bit technical. But don’t let this deter you if you really want to learn about meat. The charts and pictures are worth the price alone.
