hELLO EVERYONE,i am cooking A10lb brisket and 2- 7lb butts tonight. I will have my regular grid in its regular place, pizza stone on top of it, along with firebricks, with a drip pan sitting on top of the pizza stone. Another grid will sit on the firebrick, just over the drip pan. This is where the brisket will cook. The butts will be on a raised grid above the brisket. Should I put a piece of aluminum foil directly under the brisket so it will bathe in the pork fat drippings, or will this burn and taste funny?good Idea or bad?Why? thank you for any responses. I will not be able to check computer until this evening.
