It is obviously properly called pork roll. The philistines in North Jersey may refer to it as ham but that merely shows their lack of culinary sophistication. But what can you expect from a region which thinks stromboli is a pizza turnover and fails to properly prononce “capicola” as “gabagool”?
hey - I ain’t no philistine!! when I’d order a sub sandwich it was with gabagool!! :-)
As we used to say from the jersey shore.....they live too far from the beach.
