My buddy gifted me his Flame Boss 400 so I installed it and set it up today for the first time. Put two racks of Baby backs on the Kamado Joe set at 250F for a trial run before I do a brisket later this week. I've always been nervous with the KJ for overnight cooks because of it's tendency to flare or run out of lump and die out. So far the results are amazing and what's more impressive is that it is confirming the thermometer on the KJ dome is dead on, which I've always questioned. I was thinking of getting rid of the KJ and replacing it with a pellet smoker, but I may stick with if after all. This is a game changer.
