St. Louis-style spare ribs are the meatier ribs cut from the belly of the hog after the belly is removed. They are usually trimmed down by cutting away the hard breastbone and chewy cartilage, otherwise known as connective tissue. St. Louis-style ribs are flatter than baby back ribs, which makes them easier to brown. 8 Ribs in a 1-1.5lb packaging. Price is per pound.
