Did my first this weekend (only the flat) and it turned out great but I was hoping to get more of a smoke ring though. I have been thinking (dangerous I know)but I was wondering if I would get a better smoke ring by cooking the flat at a lower temp. initially, say around 250 until internal temp is 170 then foiling and cranking things up to the 350-375 range until done. My thinking is at the lower temp initially, I have a better chance of developing a nice smoke ring as it should take the meat longer to reach 170. Any problems with my thinking? Will the high heat at the end of the cook screw up my results? Thank for the help.
