Hey zzzdee or anyone,
I echo kland's request for a recipe, even a loose one. Just by a nice coincidence, I was in a local meat market in a small town nearby (Premier Meats in Viroqua WI), and there was something in the butcher case labelled 'porketta.' The butcher said it was a pork roast seasoned with garlic, Italian seasonings, and salt and pepper.
I didn't buy it, but after reading this, could easily go back.
Anything with cabbage and potatoes is great here in the Midwest!
