I haven't lived in Pittsburgh for 25 years, but everyone from there is familiar with a bbq chipped ham sandwich. Everyone also has their own recipe. Thought with the Steelers going on to another SuperBowl, I'd post my mother's recipe for BBQ ham sandwiches. In Pittsburgh, there is a deli called Isaly's. They are famous for their chip chopped ham. If you can find this, it's the best. If not, simply ask your deli to shave or chip their cheapest ham or whatever ham is on sale, like a cooked ham or something. You want it pretty much falling apart. This will do as a substitute. The person working the deli counter will hate you for having them shave the ham, as it takes a while, but just smile:) and say thank you. This site won't allow for me to enter chip chopped ham, but now you know what is meant:) My mother has been deceased for many years, so I can't ask her what she meant by a family-size ketchup. That's what the recipe called for. I imagine it was those glass bottled ketchups that use to be on every table, but I am unsure of the size. Sorry. I'm guessing it was the 14 oz size. Oh, and if you're making this for Superbowl Sunday, it has to be Heinz ketchup since that's from Pittsburgh:) Let me know if it works out. Go Steelers!
