Do a forum search for Pepper Stout Beef. Chuck is PERFECT for the recipe.
The last one I did stalled twice . The second stall was around 190 , and it was wrapped in a pan . When I took it out the IT was 211 . At that I wrapped and rested in a cold oven for an hour . I do think some can be more difficult than others .
I have had them to tough , put them in the fridge over night . Next day chunk it up , add sauce you like , cover it up and back in the smoker . Came out fantastic .
