Hi Popajack,
I have done 3 fresh hams in the last month or two. One was 12 lb. and the other two were 24 lbs each. I think that they were probably some of the best things I've smoked in the cookshack yet (Model 50). I first injected them with jalapeno olive oil, brine and honey. Then I brined them in a brine with honey, sage, vinegar, and a few other things. I can't remember right now. But I brined for 36-40 hours for the big guys, less for the 12 lb. Then I smoked for abourt 16 or 18 hours for the 23lb. hams to an internal temp of 175 to 180. I tried stopping at 165, but I found that they stayed moist and were more tender at 175. These hams were amazing. I sold most of them to people at work (at cost of course) and have as many more orders as I could stand to fill. I highly recommend the fresh hams, they are great.

PS I think there is another thread already about this, you might try searching for ham.
