I make lots of lonzino too. After curing, I put the dry spices on the meat, then in beef bung, truss tightly, spray until almost wet with a good brandy, then cold smoke 6-8 hours per day for 3 days. In between smokes, I put them in my drying chamber. I try to keep RH at 70%.
The lonzinos with the best flavor and texture were the ones that took longest to cure.
