I started my smoker at 250 at about 9pm, the brisket was well seasoned with salt, garlic, pepper on the meat side not fat cap, the last time I checked the brisket was at about 120 around 1am, i set my alarms and wake up to my brisket 5.5hours later at IT 90, immediately put in the oven at 350 to bring up the temp, the brisket had probe holes other than that it was intact, what should I do, im planning on cooking over the 215 IT as it is shredded brisket.
