Here are some pictures of various steps in the jerky making process.
Marinated meat ready to place on dehydrator racks
The meat in this case was marinated for 3 days and was moved around in the bag each day to distribute the marinade. If the meat is fresh you should be able to safely marinate it in the refregrerator for up to a week.
The marinated meat should be evenly browned from the soy sauce in the marinade. It is NOT dried off before placing on the racks other than letting some of the excess marinade drip off. This allows the ginger (and red pepper flakes if you used them) to stick to the meat and flavor the finished jerky.
Raw jerky arranged on rack
Here is what a rack of jerky starts out as. Try to arrange the pieces so that they are not touching, but so that you maximize the space on the rack. The meat will shrink slightly from the dehydrating process.
Each rack and the dehydrator base top are sprayed with non-stick cooking spray before arranging the meat on the rack. This will help keep the jerky from sticking to the racks as much and also make clean-up a bit easier.
Jerky ready to flip
If you look closely you'll see that the edges of the jerky are starting to show signs of drying and the underside will be somewhat dry. The underside of the meat will dry first as the heat source comes up from the base.
The jerky should be ready to flip after about an hour. If you don't do this it will make it very difficult to get the finished jerky off the racks. You'll want to flip it again in about another hour, then you just rotate the racks and condense down the pieces as needed. Thicker pieces take longer than thin pieces.
Finished beef jerky.
Here is a picture of a rack of finished jerky. If you look close you will see some small flecks of red pepper flakes. These were listed as optional in the recipe on the Beef Jerky FAQ page. If you like a little bite without being too hot, you can simply remove the flakes before eating the jerky.
The finished jerky should be dry to the touch but not so dry that it crumbles if bent. The jerky should easily last a month in a resealable plastic bag. If your house is like mine the jerky will be eaten long before that. Enjoy !
