As part of my, "lets fill the smoker to the gills and make it cry uncle" weekend, I'm going to cook my first brisket. We don't make a lot of beef in my house as my kids don't like it much and I can't eat it. My wife on the other hand loves beef so I am going to toss in a brisket since I am such a kind and considerate husband ,lol. Anyway... I was tempted to get a full packer but since this is the first time and it will only be one person eating it and i am trying out a new butcher (he has to be ok, he has a smoker in the back of his shop, lol) I just bought the flat and it's only about 5 lbs. What kind of cooking time (justt a ballpark) do you think I'm looking at ? Thanks.
