These type of pork ribs come from a pig. However, their naming convention can be quite confusing. Baby Back Ribs are the ribs that are connected directly at the top of the spine (backbone). They are located right under the loin muscle. They are learner, tender, take less time to cook and come with a higher price tag compared to spareribs but well worth it. They are curved part of the ribs and are much shorter than shorter than spareribs. Usually, the ribs will average around 3 to 6 inches in length and are shorter than spareribs. We used one rack of baby back ribs for our Chinese style garlic ribs. Pork Loin Back Ribs are labeled differently but are just Baby Back Ribs with a different naming convention. Spareribs are located at the underside or the belly part of the pig. These ribs are a bit longer, have more meat in between the bones, less meat on top and are a bit fattier than baby back ribs. In addition, they are a little less expensive than baby back ribs. You may also use spareribs for this Asian rib recipe. However, they will take a little longer to cook.
