Was going to just do 1 chuck but figured if I was going to smoke all day I might as well do 2 - so I picked up another at a different grocer. Both are bumping 2.5 lbs but appear to be different cuts based on the grain. Plus, one had some hard fat that I trimmed off. Both will be probed so we'll see how that goes. Anyway, rubbed with SPOG and planning on smoking with hickory at 235 until an IT of 150 to 160. Then into a pan with broth and foiled until 205 or so. Also I'm putting a pan of veggies underneath (until I foil the chucks) for an Au Jus. First time doing beef on the MES so I have my fingers crossed!
