    PBC Brisket Cook with Pit Temp Graph

    Hi everyone, this is my first post here. Discovered The Pit via Meathead book, and have already found it really helpful!

    I purchased my PBC just over a year ago, coming from a WSM 14.5. Was planning on saving for a stick burner, but opted for PBC after reading so many rave reviews and considering cook capacity vs. price. Honestly, my experience has been inconsistent. I've done about 50 cooks, some amazing and some leaving something to be desired. Despite my best efforts to precisely follow the lighting instructions, cook times were very inconsistent. Ribs over-done after 2 hrs one weekend, then 4 hrs to cook four chicken halves the next. Started using a thermometer to monitor pit temp, and I couldn't achieve the 270 deg - 290 deg described on the PBC website; I was either at 350+ deg or barely staying lit at 200 deg (smoke at that temp is DISGUSTING). Tried all kinds of vent settings, but couldn't dial it in. Long story short, I found the same culprit that many on this forum have found: leaky lid. Just bought some LavaLock tape a month or so ago, and four cooks in I feel like I'm starting to see some consistency.

    I cooked a brisket flat last night, probably my most successful cook yet on the PBC. In case this is helpful to anyone else, here's my process:

    1) Vent set at 1/4 open (0.5 inches at widest part of opening) for 1200 ft elevation
    2) Charcoal basket filled with Royal Oak Ridge Briquets (usually use KBB, but didn't have any).
    3) Followed fzxdoc's lighting procedure (which is SUPER helpful btw!), slightly modified with 30 minutes in the starter until corners of topmost briquettes started to ash over, 5 minutes with PBC lid off, and 5 minutes with PBC lid on (no rebar).
    4) Hung brisket for 2 hrs until internal at 150 deg F
    5) Transferred to 225 deg F oven, no crutch, for 11 hrs
    6) Rested for 1 hr, sliced and devoured

    The spike at 2:24:00 is when I removed the cover to pull the brisket. Ambient temperature during the cook was 5-10 deg F (Minnesota).

    Neat. I should have ordered my Therma Works Data logger when the wife was out of town

          A hearty welcome from Illinois.

          There are beaucoup PBC users here that are more than glad to help you. You just need to ask the question.

                    Welcome stev ! Were you cleaning the inside of your lid between cooks? I had this problem in the beginning but once a nice layer of sticky goodness formed on the lid my leakage problems went away.

                      Thanks for the welcome everyone!

                      HawkerXP I wasn't cleaning the lid, and the grease buildup helped a little, but I was still seeing smoke seeping out from several spots around the lid other than the rebar holes. The LavaLock gasket has taken care of that. Kind of frustrating to need to use an aftermarket gasket, but given the price of the PBC it's still a great deal.

                      Several members here have posted that lid seal/rebar hole size have much more effect on PBC pit temp than vent adjustment, and I would echo that.

                        I, too, have been a bit frustrated at my PBC's lack of consistency, where I had very consistent results on my Weber kettle all last year. I may try that gasket next; thanks!

                      stev If you don't mind me asking, which LavaLock did you purchase? There are several thicknesses/widths available.

                        Dint buy a gasket. You don't need one. And they wont work as well as a "grease gasket."

                      stev , thank you for the nice writeup. That brisket looks awesome.

                      Whenever I hear PBC temperature inconsistency, I immediately think of a leaking lid as the culprit. My PBCs (I've had 2) did not have leaking lids when I got them, but my current one developed a lid leak after a couple of years of use. I used to foil the lid rim area where the leak occurred, but got tired of doing that and installed the gasket.

                      I never had inconsistent temperatures because I jumped on that leaky lid problem right away when I noticed it at the beginning of the cook.

                      For new PBC owners, there's a lot more happiness if you can ensure that the lid does not leak. Mine leaked in the area of the rebars on one side, so I'd hold a piece of cardboard over the rebars (to block their smoke) so I could see see if there was smoke coming out of the lid seam in that area.

                      The second way for a new PBC owner to ensure happiness is to use a remote thermometer to measure the PBC's cooking temperature. Most PBCs most of the time cook evenly and consistently. But if the temp starts going south (or north, for that matter) for whatever reason, getting on it right away ensures a successful cook.

                      The PBC is a solid cooker, but like everything in life, it's not perfect. Sure turns out good food, though.

                        The roll is long enough for at least two PBC lids, maybe three. Hope it helps you. You're probably already doing this, but definitely follow fzxdoc 's lighting procedure as it eliminates a lot of variables.

                          Yep, I've used her method several times with the same inconsistent results (NO offense, fzxdoc !). My next few, I'm going to attempt the OCD stacking of the coals, per Spinaker in a recent thread, and tweaking the vent hole a bit.

                          No offense taken, abandonedbrain. If you have smoke leaking out in the rim area, that would certainly cause inconsistent results.
