Cooking a 15.8 lb brisket (just my second time doing brisket). Smoking at 225 and was planning on 1.25-1.5 hours per lb. 12 hours in the probe is at 190. This seems too soon since I was planning on 20-23 hours. What is the best plan to finish it now and eat in 10 hours. Leave at 225 until it hits 200 then leave on keep warm setting (165) until we eat ?
