Cooking a 9lb butt right now. Setup is AR with extender. Stone has been getting covered with fat lately and takes a while to burn clean so this time I put in a drip pan to catch some dripping. Got the Maverick up and running. Maverick is showing 235 grate temp which is great but the dome on my new Smokeware is showing 200. I have usually had the opposite (dome a little higher than grate for a few hours or more until they flatten out). Only thing I can think of is the meat is so high in dome and it is ~40 IT that it is throwing off dome thermometer as they are close??? And no it is not piercing meat. Thoughts? Never had it backwards like that.

    Just a thought where did you light your fire and if you run your hands around your dome is the heat consistent and esp. where your dome thermo is..

    Same as I have for 6-7 years on egg. Right in middle of lump. Only changes are new Smokeware thermometer. Butt on extender so I can fit a drip pan. Drip pan also out of ordinary for me. It is cooking fine so I could care less just wondering if any of you have ever seen same thing with reversed temperatures. @johnmitchell

    @Chubbs -  I had a similar experience yesterday with ribs.  I had a rack up high on the extender and 2 below. My grate temp was a good bit higher than my dome.  For the finish, I sauced and put all 3 racks at the felt line and removed the extended.  Then my grate and dome temps were both around 275.  I think it has something to do with our food being up in the dome.  Maybe it's the air in Columbia. :)

    My guess it the drip pan has changed the air flow around your grate probe.  Grate temps will vary a lot depending on their placement in relation to the meat, edge of egg and drip pans.  You changed two things - the dome thermometer and adding a drip pan.

    In cooking, often we implement steps for which we have no explanations other than ‘that’s what everybody else does’ or ‘that’s what I have been told.’  Dare to think for yourself.

    Yeah that is what I am thinking. I will go halfway through and remove drip pan and extender I think. Strange for sure

    I think having the big chunk of cold meat high in the dome affects the dome temp more than we would expect.   I put a turkey on a raised grid and coul

    I've had the two temps swap places during a cook ... the dome temp started out higher and finished lower than grate ... 20 plus degrees difference at both ends.  Even if you start the damn fire in the middle, nothing guarantees that it will stay there.  Plus, any thing new/extra in the egg will screw with change airflow.

    Dumb question, but you did try out the dome thermometer from your mini just to double check the new thermometer?

    I have put all 3 dome thermometers in and all are within 5 or so degrees of one another. Yeah I have always had about a 20 degree differential but always dome higher than grate until later in cook when they get the same or close to it.

    Sounds like too many indications for me.  But if all are calibrated then "what you see is what you get".  I'm sure it will turn out just fine.

    I agree.  I quit worrying about grate temp quite some time ago.

    This has happened to me before but only on my small egg. It always corrected itself eventually.

    I don't care about it either but a lesson for sure-- albeit odd one. 

    Update--Removed the extender and still reading the same-- grate is running about 20 higher than dome regardless of where I put the grate probe so it is/was not reading meat temp. I could see someone finishing their cook way earlier in a situation like this if they are not measuring grate and are actually cooking hotter than they think. Again, I could care less, but a lesson for sure. As always go by the internal temp of meat but also in BBQ things change. No matter how many times you have done something got to be prepared for anomalies. I like it. Oh and @Gamecockeggman, bloodys started at 9am so good there too!

    I always saw the difference in temp between the grate and dome and started connecting my grate thermocouple thru the daisy wheel to the dome thermometer.  Even doing that, it takes an hour or more before my Guru grate temp and dome thermometer equalize.  Go figure.  I still set the Guru at 240 for low and slow and haven't noticed a difference.

    Any road will take you there if you don't know where you're going.

    As a rookie I got use to the egg using the original equipment, I guess you could say very confident, then I started using all the aftermarket stuff that everyone talkef about on this forum,  you talk about confidence going to he'll in a hand basket. What saved me was monitoring thr internal temp.Even using the new ash basketnchanged the way my egg came up to temp.I have enjoyed all the challenges that have come my way.

    Well by the end of the cook it completely flipped. 300 dome 250 grate. Very perplexing cook but this was some of the best Q I have had in a long time. Made Ruhlmans vinegar BBQ and it was on point.

    I think your dome thermometer is dyslexic.   =)
