I used no recipe for these, just kind of winged it I guess. I injected the shanks with a garlic herb marinade and let them sit overnight. I made a rub of sage, rosemary, thyme, paprika, sea salt, and black pepper. I hung them in the smoker with bacon wrapped around the top of the shanks for a self basting kind of thing. Smoked them for 4 hours at 240. Then I foiled them with about a cup of Guiness. Put them back in the smoker for about an hour and a half. They left a nice juice in the foil that I reduced to make my Guiness sauce. At this point they were very tender and moist. I put them back in the smoker to caramelize the outsides a bit. They were very good! The whole family loved them, and it was a great meal. Thanks for lookin!!
