I cook hunt and cook quite a bit of duck during the hunting season using my WSM 18.5. I have found that the KEY to successfully cooking a duck is to brine it for 24 hrs. prior to smoking. Duck has a very low fat content on it and must be brined to assure the meat stays moist. Also, I smoke it...
Threw this bad boy on the WSM tonight. Used applewood for a light smoke flavor...Brined for 2 hours but would've done 24hrs. if I had the time.
Pre-Smoke
Post-Smoke...145 Internal Temp.--Thermapen
Mission Accomplished. Roasted Broccoli and Feta Orzo for some sides.
