Pork ribs that are taken from the whole spareribs of the hog, which have had the brisket bone and some meat surrounding it removed so the cut appears more rectangular in shape. When this cut is processed the small tips of meat trimmed from the ribs are available as Brisket Bone Rib Tips. In comparison to whole spareribs which can weigh up to 5 pounds, the St. Louis Style Sparerib will most often weigh up to the 3 pound range.
