Happy Easter to all. I started to smoke a 17 lb. brisket and everything said 1-1.5 hours per pound. I started the smoker at 225 at 4:30 in the afternoon but by 11pm the internal temp was 174. I lowered the temp to 175. Woke up at 6 am and the internal temp was at 140. Raised the temp to 200 and now at 10:30 am the temp is at 163. Will this brisket be ok since the temp dropped?
