PS: Our 'corned beef' (= American 'bully beef') is made from the same stuff (i.e. salt-cured brisket of beef) but then finely minced, pressed and held together by gelatine.
My link says "You can assume between 2-3 sandwiches per pound". Taking a mean, of 2.5 sandwiches per pound, at $34 per pound, makes the meat content of one sandwich come to $13.60 (= just under ten quid). You've gotta like your sarnies at that price!
It was a long time ago 2000s when I was last in America and I remember at a party - we gathered on the lanai - corned beef was mentioned but when it appeared it didn't look like ours - more like a ham shank per se.
