Don't know if I have shared this or not. When I make jerky, I use venison burger instead of the strips. I find that it is much easier to do, and the stringy strips don't stick in my teeth like traditional jerky. Same method; mix with seasoning, press into 2X6 strips with form, put into dryer until dry, put in glass canning jars, and into freezer until I need them.
Used to make jerky (venison) when the boys were trucking and never had a problem - but since no deer been using beef and have had a few batches that the curing salt really comes out when freeze, if just leave in fridge ok just my 2 cents worth.
