Doing my first baby backs ever today (2nd BGE cook overall), 2 racks using 3-1-1 and Dizzy Dust rub.
Everything going fine so far. After 3 hours at 250 dome, I open the lid to foil the ribs. While I am doing that (with the lid still open), suddenly white acrid smoke (like when you first light the lump) starts pouring out which it had not been doing before. Seems like some lump that hadn't been lit caught flame when the lid was open.
I left the ribs off the grill in foil for a few minutes, took the daisy wheel off to let the smoke clear, then put the ribs back on after it had cleared (about 15 minutes).
Does this happen to others? Was my mistake leaving the lid open while foiling the ribs?
Will post some pics after they're done! (Smell great)
