Ive never seen this cut around here. CCR's are more in the back and frequently contain some of the upper loin
this seems to be butterfly'd pectoral muscle where it connects to the sternum
and Ive never seem pork pectoral muscle, i.e. pork brisket.
back some time here on eG someone found it as a corned product brined in a pouch.
it must go into hot-dogs and the like ?
it would be interesting to find some, and if reasonably priced, SV it a la Beef corned beef
it might make an interesting sandwich !
