I completed my first batch of beef jerky using the "James Jerky" fan attachment. I used the recipe within this post for the marinate. The beef jerky turned out great, nice and dry, but not too dry, moist and chewy just like we like it. I did omit the chili pepper flakes as my wife and kids don't like it spicy and I also the liquid smoke since I was smokin it.
Each strip of meat was about 1/8th of an inch thick
Marinated for 36 hours (24 will do)
place each strip flat on the rack (used all 4 racks)
Added 2 - 2.5 ounces of apple wood chips and set the smoker to 160
Smoked for 2.5 hours (without the James Jerky fan)
After the intial smoke, I drop the temperature down to 140 and added the fan attachment
Jerky was ready 6 hours later (total time from start to finish = 8.5 hours)
Pictures are shown below.
This is the first batch of beef jerky, for the second batch which I will complete tomorrow, will try 170 for the first two hours, then drop to 150 - 160 with the fan to see how it turns out.
