After about a years worth of research, advice from Dennis, I smoked my first prime brisket on a 23 Ultimate. The results were outstanding.
Rub - 2 to 1 Pepper to salt. Before mixing, I subtracted 1 TBS of salt. Rub applied liberally. Then lightly sprinkled with Lawerys followed by garlic powder.
Dry brined in the refrigerator uncovered for 24 hrs.
Fuel - Jealous Devil, hickory and cherry wood chunks at the bottom. Harry Sooβs method.
Drip pan with water and spritzed with apple cider/water combo 3 to 4 times. Rumor has it itβs not needed, latest scientific info says it essential.
Once eye burning smoke cleared to white smoke (10 minutes) placed cold brisket onto cold grill. Turned Blue in 1hr. Not all white smoke is bad - latest finding.
15lb brisket trimmed down to 10lb, smoked 9 hours at 230 Meater probe temp increasing to 250. FireBoard controlled the fan. Meater used to monitor the meat.
Pulled at 190.
Wrapped in tallow/butcher paper. Rest 15 hours in a wet oven/cooler.
Done.
