Beef Jerky help

I cook mine at 190 indirect for about 6 hours. I have been using cube steak but am going to try top or bottom round next time. I did a post it a while back.

Try to stay under 180 if possible.  What I have found:
A good grid temperature reading is absolutely imperative.  You cannot rely on the dome reading.  I spread out my coals, no different than any cook and light one weber starter cube in the middle of the egg.  Also spread out some wood chips within 4-5 inches of the starter cube.  After the starter cube is lit (and I've got a couple pieces of charcoal over it), I put the plate setter in and shut the lid, with both dampers still wide open.

Once my grid temp hits 110 degrees or so, I shut the daisy wheel and bottom vent to a small opening.  The shutting of the daisy wheel will cause the grid temp to raise in the short term as the heat becomes distributed in the lower levels of the dome.  Continue to monitor temp to about 140, which is when I put the meat on.  At this point, I am also using getting some nice smoke from the wood chips.  I don't know what size egg you have, but on my XL, the daisy wheel oval openings usually about 1/8 of an inch open.  The bottom damper is usually around a quarter inch or less.

As long as I don't go over 180F near the grid I have had success.  Over 180F seems to change the texture of the jerky.  Still good, but not as good.

This last weeks cook, which consisted of 4 trays, took 10.5 hrs at around 155-165F.  I have now started to cheat by using a DigiQ, but you can do it without it.  Just be aware that even slightest winds will impact your temperatures.

Good luck.

Hey BuckeyeBob...not sure where you are, but I am in central Ohio.  I have been using LEM Backyard seasoning as a base.  I then have made some changes by adding in some Jamaican jerk spices that I picked up somewhere (I honestly can't remember...may have been in Jamaica.) for some added flavor and just a bit of heat.  I use instacure #1 (the pink stuff) to make sure I am doing what I can to keep people healthy.  I will probably move away from the LEM seasoning at some point, but I will need to replicate the taste, because everyone loves it.  I use LEM racks, which can be found at Gander Mountain.

I rotate the racks every 2-3 hours or so depending on my grid temp.  One piece of advice.  Open the lid, take all the racks out at once and shut the lid as quickly as possible.  Rotate the racks outside the egg and then quickly put them back in.  This helps minimize the temp variations.
