Thanks for the replies guys. Yes I am sure my thermometers are correct. Its 1:45pm here in NY now and the temp seems to have stopped rising as rapidly. The internal temp is now 172.
Ok so I am trying my first brisket smoke. Put it on at 9:20am. Internal temp is already up to 160. Is it me or does that seem like its going too fast. Temp at the lid when I put it on was 200. Its jnow up to 225.
