Thanks Tom. Based on G Que's rec, I did find some great-looking recipes for oxtails. I was looking for a deep smoke flavor and a one-shot meal from the smoker. I have found some ideas and will follow through and post when I can. I do appreciate your idea about heavy smoke in the AQ for a short time to get just a flavor on oxtails (or anything!) cooked through by another method. I intend to try that one too. Do you think surface bitterness would be a problem? I'm thinking of trying it on a small beef round roast I don't know what to do with, to partially roast it in the oven, then your smoke idea, followed by a quick sear on the grill.
