NOTE: I personally feel that the flavor is too mellow when mixing per the package instructions, 2 1/2 teaspoons per pound. I use a heaping tablespoon. You may want to first make a pound per the package instructions and see if you want a stronger flavor.
Place beef in a resealable bag or container.
Place meat, seasoning, curing salt and water into a mixer and mix for 5 minutes.
Transfer meat to a resealable container or bag and refrigerate for up to 8 hours, massaging every hour or so to get the marinade distributed and absorbed evenly.
Remove meat from the marinade. Add to a jerky gun and squeeze out onto Nesco trays.
Add the dehydrator top, set to maximum temperature setting and dehydrate for 5 hours, rotating the trays (bottom to top) every 2 hours or so.
To test for doneness remove a piece and let cool slightly. Try to bend the meat. If it gives and starts to tear at the bend it is done. If it bends without tearing return to the dehydrator and let it run another 15 minutes and test again. If the meat is crunchy it is overdone but still good. It's really personal preference as to how you like your jerky. Soft, chewy, crunchy. There's no wrong here.
Let cool before storing in an airtight container.
