I just musturded (word?) and seasoned a frozen brisket. As per a suggestion I saw here, I put the probe in hot water to heat it up so it would pierce the frozen brisket...it worked! But, as I just started the Amerique, it dosen't recognize that the probe is there. I suspect it is just too cold in the frozen meat for it to register. So I set it to cook by time initially. It will be interesting to see if when the meat warms up, the Amerique automically recognizes the probe and changes to that cooking method, or if I have to 'reboot' the smoker to get it to use probe mode, or if we have a probe problem Huston! I'll post the results later.
