Today is my first attempt at smoking anything. I've seasoned my char broil electric smoker. Today I'm trying to smoke a small 4 lbs brisket. Everyone makes it sound so easy. how long do I leave it in the smoker? I'm planning on 2.5 hours in the smoker at 225 then wrap in foil and 2 hours in the oven at 225. Then I'll let rest for a hour and slice. Does that sound alright? Help guys?
