[quote=Goodenuff][quote=spoonerpa]I use a circular dehydrator with the heating unit and fan on the bottom. When I make venison jerky, I rotate the racks from bottom to top every 1.5 to 2 hours. until the jerky is where I want it. I have five racks so, it usually takes about 8 hours to complete a drying session. This reminds me that I have 2 backstraps vacuum packed in the freezer for making jerky.[/quote]The backstraps, which I would call the loin, are the best part of the deer. Venison chops or larger cut to roast/grill and slice to serve would come from. Very tender.
IMO, it seems like a waste to use the best and one of the most tender cuts for jerky when it can be made from other parts of the deer. Personally I use the round, shank, flank or shoulder for jerky.[/quote]If "backstraps" = "loin", I would agree. It would be like using filet mignon to make jerky. The best cut (for me) of beef for jerky used to be called London Broil. I don't see it anymore by that name. I usually wait and buy eye of round for jerky when it goes on sale. Both London Broil and the eye are very lean, but are tougher cuts that come from the rear (round) of the cow.
If one wishes, you can tenderize the tougher cuts with Bromelain (ground fresh pineapple) or kiwi, but if you do, do not marinate with these for more than 2 hours or the meat with literally fall apart.
My personal choice for jerky is usually a teriyaki style marinade, and if I were to tenderize with either of the above things, I let the meat marinate in the teriyaki for a couple days then add one of the above for the last hour or so of marinating time.
