I've had a 1lb chuck roast sitting in the freezer for a few months (it was what remained after I cut up a larger one for stew meat) with no idea what to do with it. I'm making a pot of chili tomorrow so I decided to smoke it, put it in the fridge overnight, and cube it up tomorrow to go in the pot.
I rubbed it with chili powder, red hatch chile powder, cayenne, smoked paprika, coriander, cumin, and s&p. Into the smoker with a chunk of red oak courtesy of a friend down the street who had a tree in his yard removed due to damage from hurricane Zeta. It stalled at 155, so I put it in a tray with some homebrewed jalapeno-lime lager, wrapped it, and took it to 190.
