Spareribs are the meaty ribs cut from the belly of the animal after the belly is removed. They are usually trimmed down into the popular St. Louis-style spareribs by cutting away the hard breastbone and chewy cartilage, so the slab is more rectangular in shape.

Las costillas con corte estilo St. Louis son la parte restante del costillar pero dejando de lado las puntas para que quede con un corte de forma rectangular.
