I have to have two briskets smoked and delicious for party on Sunday. I have smoked a 10 # brisket and it turned out well but never tried two at the same time. I plan to cover them in rub on Sat morning and let them sit until about 7 PM Sat night. Put them on at that time at 225 and hope they are at 190 IT by 3PM on Sunday. I intend to smoke it heavy for the first 4 hrs and then evry few hrs add a few more chips. Any suggestion would be appreciated.
