top grate - ?bottom grate - ?
i am going to check the temps again in half an hour when the 8th hour is up but i am sure the mini is either hotter or out because i had a heat spike just after taking out the chuckie.. i can easily do pork butt of size on this knowing that i would have to add some more charcoal if it got past a 10 hour cook.
top grate 175*
bottom grate 225*
i still had the vents open only about 1/4 of the way...there is probably still around 1/4 charcoal of what i started with, if i moved them around i could get temps back up and continue...a long cook is without a doubt possible on this cooker. i dont think i even used 3lbs to get to 8 hours..i filled it up without packing it tighly to the bottom of the lip of the smokey joe. i will take pictures tomorrow of exactly how much charcoal is left.
after the cook
plenty of coals left
