There is an unwritten trick to making jerky strips from burger = ground up meat ('mince,' whatever you like to call it) :
You know how burger has a granular texture? Cooked or dried like that, it's really crumbly?
Add the cure and seasoning to suit yourself. To mix it in, put on a pair of those cheap disposable vinyl gloves.
Mix and mix and mix and mix and mix.
Mix until you notice that the meat is no longer granular, that it is now really stringy.
The "stringiness" is what holds it together, even in hamburgers on a grill.
Load the pistol and get busy. I use double size cake racks over sheet pans for the oven version.
I do the same for meatballs, dolmades, kefthedes and so on. They really hang together and this does not make for a tough texture, either.
I was just as sceptical as you are when it was explained to me. As a matter of fact, it really does work as expected!
High Mountian Brand: Original spice mix. Peppercorn spice mix is too zippy.
Buy one of each and mix them together. Goldilocks would be pleased.
