Boston butt

A Boston butt is a slightly wedge-shaped portion of the pork shoulder located above the standard picnic cut. It includes the blade bone or may be sold as a boneless “lean butt,” and it can be used as a substitutes for tenderloin in certain preparations. The pork shoulder is generally classified as a primal cut, with the picnic and butt portions considered sub-primal cuts. Some sources, however, refer to the butt itself as a primary cut.
