Was kind of busy yesterday so I didn't have time to fire up and tend to the Santa Maria pit for tri-tip, so instead I smashed up some mesquite lump charcoal and mixed it in with the pellets on my pellet grill. About 30-35% charcoal, the rest Lumberjack Oak-Hickory-Cherry pellets.
Tossed the tri-tip on at 175ish w/ smoke to an IT of 140 (about 4-1/2 hours). Quick finish with the searzall and holy crap, this came out way better than I was expecting.
(the camera in my phone isn't that great, the color is off in the photos, the meat was actually pink, not brown.)
