You made a beautiful looking Coppa and your wife loved the taste. What more do you want.!!! Just dry it some more. Here in the Sub Tropics I do the same as Troy with large Salamis. I only wrap them in white paper towels and then pack them in brown paper bags and into the fridge until they have lost some more weight.
An old butcher friend of mine that makes Coppa’s will only sell them at 50% weight loss. No queries or complaints then from his customers.
