I wanted to try something different so I picked up a 4.5 lb. pork roast. I'm thinking that I'll smoke it with Hickory and leave it in a pan since they produce so much juice. I want to slice it or chunk it so I guess that I should only take it to 160*. Also, I'd like to add some potatoes to it at some point but I don't know when. I don't think it will need much seasoning either -- maybe I'll stick some garlic slices in it and hit it with some salt and CBP. When should I add the potatoes? Should I cover it with foil at some point? Should I add some liquid in the tray? Any suggestions are greatly appreciated!
