Pork spareribs come from the chest of the pig, and are attached to the sternum (breastplate) before removal. They are the meatiest of the ribs, and have the most flavor. Back ribs, or “baby” back ribs (AKA loin ribs) come from the central section of the pig, beginning where the sparerib ends, almost connecting to the backbone. They are much less meaty, smaller, less flavorful, more expensive, more tender (but much more likely to be overcooked and dried-out since they have less self-basting fat), and more likely to be glazed with some kind of gloppy sauce. Baby backs are the rib fodder butchered for your neighborhood national chain restaurant menu, and they have nothing to do with the age of the pig. Ribologists avoid these types of restaurants, and their puny rib offerings.
“Country style ribs” aren’t technically really ribs, but are cut from the blade end of the pork loin They do have sections of the blade bone running through them, and come from an area right next to and above the head end of the spareribs. They are good and meaty, if a little lean, and grill much better than they barbecue, but they are not ribs (even though the supermarket says so).
A whole rack (AKA “slab”) of spareribs has the breast bone and cartilage intact, and any meat cooked with bone and costal (rib) cartilage equals more flavor. If the breast bone and cartilage have been trimmed off, the rack is called a
Spareribs are sold wholesale by weight, and have their own size terminology: “3½ and down” is a rack that weighs less than 3 and a half pounds, meaning it came from a younger and more tender pig. A “3 to 4” or a “3 to 5” is a slab that weighs between 3 and 4 pounds or 3 and 5 pounds. The bigger the slab, the older the animal, and the lower and slower it should be cooked to maintain tenderness. A full rack of spareribs should have between 11 and 14 ribs, and should feed between 2 and 4 eaters, depending on their rib-storing capacity. Figure on losing about 25% of your total rack weight when you cook a slab of ribs.
Fresh is always better than frozen. All-natural or organic is always better than water-injected, antibiotic and/or hormone-laced pork. Reject “enhanced” slabs…packed with water, sodium phosphate, flavorings, and tenderizers…you want real meat. Heritage breeds such as Berkshire, Mangalitsa, Tamworth, Red Wattle, Duroc, Old Spot, Yorkshire, or Large Black will taste a lot better than one of these new hybrid disco breeds. Avoid “shiners”: ribs that have been trimmed so close by the meat processors that the bones show through; these will have little actual meat to consume. Look for slabs that have good meat coverage and nicely-trimmed fat shells.
Regardless of how you plan on cooking the ribs, or what you might be flavoring them with, the membrane on the back side of the ribs should be removed before seasoning. The sheath-like membrane covers the back side of the slab. Once removed it allows the seasonings and smoke to penetrate the meat easily, and makes the rack more tender. To remove, use a blunt-edged knife and pry up one corner of the membrane. Using a thin towel or a paper towel, firmly grasp the corner of the membrane and pull it off. One removed, the rack is called a “skinned” slab. Some folks prefer instead to make a series of shallow cuts with a sharp knife through the membrane. We like them skinned.
Slow and low smoking is preferred with ribs. Some folks steam them first, to break down connective tissue and remove some of the fat. Do this only if you are in a big hurry, and if you do it, save the de-fatted liquid from the bottom of the steamer. It makes a killer base for Chinese hot and sour soup, or for some székely goulash.. Some folks do it bass-ackwards: they smoke the ribs, and then wrap them in foil to finish them. This is, in effect, steaming the ribs, except that you ruin the nice smoky bark you have going on the outside. If you're going to ruin them with a glaze or a gloppy sauce, no loss, since you'll be destroying the bark anyway. There ought to be a quarter of an inch of bone showing on the end when they are done. The bone should not slip out of it's meat wrapper...if it does, the meat is probably overdone and mushy.
So, stick to a real sparerib for maximum flavor, and slow smoke them over some oak with a little wet fruit wood added to the edge of the coals. If you must have sauce with your ribs, add it when you eat it. Anything else violates all the rules of nature.
