I am cooking a 15 pound brisket for guest2 on the 3rd. I has planned to cook it outside on a grill/smoker the day before. But Tropical Storm Alex is here and likely to hang around all weekend. So I will need to cook it in the oven with a little time on the smoker to give it a little smoke flavor. Should the brisket go on the smoker first or after the time in the oven?
