The shoulder I received was larger than a typical commodity shoulder that arrives two in a vac-packed bag. This was again from Slagel Family Farms and included the front end of the rib cage and the neck bone. The piece I would trim out for this coppa would include the butt end of the loin.
The left top image shows the whole piece I received. On that picture, the piece I want to remove is the top right between the bone and skin, as it tapers from back to front. In the top right image I removed the bones and the desired muscle is exposed. The bottom left image shows the muscle once removed and the shoulder that remains. The last picture shows the removed muscle to use as a single cleaned piece.
I then made and chilled a brine of cure no. 2, salt, sugar, bay, fennel seeds and black peppercorns. I brined the coppa for a week. Once it came out of the brine I dried it off and rubbed it with a blend of fennel, black peppercorns and paprika. It was then stuffed into a medium beef bung. You can see the bung above partially filled with water so you can visualize its size. They come salt packed so the usual soak and rinse method is employed here. As the picture shows, you can easily fit your arm into the bung.
Once it was rubbed and stuffed I squeezed out as much excess air as possible and tied it off at the top. I then poached it in simmering salted water for an hour. I left the boning knife next to the cutting board for a size reference above.
After it cam out of the poaching liquid I used a sausage pricker to get the remaining air-pockets. I then hung it dry out the wet skin. It stayed in a well-ventilated cool place for about 72 hours.
After the brief drying period it was moved into the refrigerator to hang until use. Once you are ready to slice, simply remove/peel the dried bung from the coppa. After that you slice it fairly thin and enjoy as you wish. Slice it as close to shaving while maintaining whole slices. I laid my slices out on a platter (shown at top) and offered small rolls and a spicy mustard.
