It wouldn't surprise me if Dom did seek out the ezzo, which I think is the best of the best, but in more probability it is the high end of Hormels line of pepperoni called Rosa. It is quite popular around the NY area, cups, chars, and it tastes really amazing. Ezzo is very similar, but just a bit more porky if that's a word. I see it on most of the better pizzeria supply product listings, but never Ezzo. There are two sizes, the narrow rosa and the standard sized rosa grande.
