The fresh coppa, often labeled the pork collar, is a cut we have used in the past. It is mostly seen in restaurants. This is the first time we carved it out of a fresh pork shoulder to play with at home. We cooked the coppa from our pork shoulder for 24 hours at 57°C. The meat remained juicy and the connective tissue broke down and converted into gelatin. The next day we sliced it, seared it, and thoroughly enjoyed every bite.
