2. Add ~ 1/4" of liquid such as water or beer to the pan before foiling.
3. Pan and foil at 160 to 165.
4. Start checking for tenderness with the probe at ~ 185. You might have to go up to 200 to reach the point where the probe inserts like it is going into a soft stick of butter.
I have cooked a lot of excellent briskets using the high heat method, mainly because I do not have 12 - 15 hours to spend on it due to my work load. You can also cook a great brisket using low and slow, i.e., maintaining a pit temp of ~ 210 - 225. Be prepared to spend 12-15 hours if you do it this way, possibly longer for a big brisket.
If I can be of any more help, I would be more than glad to. I have certainly received more than my fair share here.
calibrated all probes in boiling water and all accurate.
