Here you go Wessthemess,
The recipe is called High Plains Jerky and is on several websites. It has been my goto for the past several years. Never seems to turn out the same way twice for me. Sometimes more sweet, sometimes more pepper. Probably has to do with me playing around with the ratio of brown sugar and black pepper.

But it is always good! I usually use London Broil but recently I have been experimenting with other lean cuts.

Tom Jackson of ATBBQ recently posted on "the sauce" a video making some jerky on the YS640. Good video as it shows the YS640 in action.
Hope you enjoy.
