My chuckies turned out very flavorful but a little on the tougher side. Not real tough but not pot roast tender. I created my own problem because I forgot to kick the temperature up like Smokin suggests once I cut the smoked roast into pieces and placed them into an aluminum pan with the Au Jus.
I did place the leftovers into a crock pot with a little of the Au Jus mixed with barbecue sauce. After 5 hrs on low, they turned out real flavorful and tender. I froze them and will throw them in with the next batch of Smokin's BBQ Beans.
