Pappy, somewhere around here we had a thread about tongue and some other cuts of meat that used to be "po' folks" food, Not any longer. Seems the foodies have found out how good some of that stuff tastes and now it's in short supply.
Bone broth recipes makes it so the butcher counters no longer have bones for free if you ask, "oxtail" no longer in the discount meat section.
Good thing for me, whole chickens and turkeys usually come with the backs and necks.
