Well I did my first powercook myron mixon brisket. He says to hell spending 18 hours on a 14 lb brisket.
Injected it with the beef broth injection, set over night
Put the rub on and let set in the fridge for 4 hours
Meanwhile brought the smoker up to 350 degrees and got the smoke rolling
Maintained the 350 degree heat for 2.5 hours
wrapped and let cook an additional 1.5 hours until the temp at the point was 205*
Took it out wrapped it with a blanket for 1 hour, her recommends 4
Actually one of the most tender brisket's I've done compared to the 225 method
