Frequently Asked Questions
St Louis ribs are flatter and straighter, whereas the baby back ribs are curved and shorter. Because the St Louis ribs are flatter and easier to brown and get just right on the grill, they can cook more evenly, which is excellent. They also have a more succulent and fattier characteristic.
From the 1930s through the 1960s, smaller meat packers in St. Louis created a new, more rectangular cut for pork spare ribs that included more meat and removed cartilage from the side of the ribs. They called them the St. Louis–style ribs cut.
