I am very new to smoking only had my Masterbuilt 30" electric for about a month now. I wanted to try jerky this weekend so i got a 3lb rump roast cut it into strips about 1/4" thick. Had the smoker set at 190 and i used hickory chips. I also did not use the water tray. I added chips in the beginning and then about 45 min into it. I let it smoke for 3 hours. When i tasted the jerky it is not good. Its VERY dry. Not very good flavor. My questions are obviously why did this happen? Did i cook it at too high of a temp? Did i use too much wood chips and it got too smoky? should i have used the water pan? If anybody have any help would be much appreciated.
