Started smoking my very first brisket this morning (2nd thing I've ever smoked in my life). I'm using an electric smoker with the temp set to 225. Everything has been going perfectly today. Got through the plateau after finding out it should do that. Wrapped in butcher paper after it hit 170 and waited for 190. The waiting is kind of over but the brisket appears to only be partially done. The point is at 192 but the flat is at 175. And I've moved the temp probes around to different places and I generally get the same temps. The probe glides easily into the point but there is still resistance in the flat. What should I do?
