I was just given a Brinkman Gormet electric smoker. This isn't my 1st choice for a smoker, but I am kind of in a bind for this weekend, so I need to use it.I plan on giving it to my 10 year old after I use it, to go with his Weber grill. I have 60 pounds of butts to smoke, and I can fit all but 2 butts on my small gas smokers. My big smoker isn't finished to my likeing, so I really need to use the Brinkman. My question is this: since there is no thermostat on this thing, how long "ball park" can I expect for the butts to cook for (190 degrees internal temp, I want to pull them) on this smoker? I have never used this, and I don't even know where to begin. I want to be sure I give myself plenty of time. The butts are around 7 1/2 pounds each. I normally use around 12 hours at 250 degrees on my gas smokers, and they turn out perfect.
