man.. its so great the way the whole world is chiming in.. its been a while since we walked someone thru the whole cycle start to finish.. brings back the ole times :eusa_clap :eusa_clap.
TB.. i am not sure if this was mentioned in here, but your door thermo is reading 250, thats great... BUT DOUBLE CHECK the temps at the grate where the meat is.. use an oven thermometer or something. Your door can say 250 and it can be 300 in the middle of the grate. Eventually, you will know what your actual pit temps are when the door thermo reads 250.
Also, once you find your 'favorite' temp.. (we all range from 215-270).. We all cook at different ranges... IMO, its not that important.. RANGES are whats cooking. Im not so picky... 230.. 250.. 255.. who cares.... as long as your NOT real low.... and even the high side over 300 has its place(and technique) which you'll learn later on. Anyway, once you find your favorite spot on the thermometer, rotate the thermometer so that spot points straight up at 12 oclock position. That way, without caring what the number says, you can glance at the thermometer form across the yard and as long as it says 12 oclock, you know your ok.
When u get a chance after this cook, buy some pop-n-fresh biscuits. get about 20 of them. fire up the bandera and bring it to temp. then place the biscuits on farious places on different shelves. Observe how the biscuits cook. this will map the chambers characteristics for you... where your hot spots are and where the cooler spots are.
Enojoy the day.. ! we're all watchin and livin our first day again thru you.
