I have never tired the dehydrator method, just cus I was not a fan . I have always used a smoker and High Mountain Seasonings.
QDogg's method of making Jerky never fails for me. However, the seasoning and method should work just as well with a dehydrator.
QDogg's Jerky 101
Jerky 101
Start with 5 pounds of flank steak.
I've tried almost all cuts of meat and I keep going back to this. I use High Mountain Seasonings cutting board and knife kit for a consistent cut. Along w/their seasonings, Inferno (not as hot as you would think) and hickory in this batch. Their website: http://www.himtnjerky.com/ I have tried other cures, and these are great and very consistent.
All of the meat cut into desired strips and in zip lock bag curing for 24 hours. Make sure you go the full 24 hours and turning the bags a few times.
Put the strips in a smoker or your dehydrator. My smoker takes about 6 hours to get the right dryness.
