For this tutorial, I chose to make jerky from goat liver. A 500 gram piece cost me $2.02, which is pretty cheap. You can use this method for any type of organ meat like kidneys, hearts etc. The actual preparation time for these treats was about 45 minutes, not counting the boiling and drying of the meat.
If you make the liver pieces small enough, this can be a suitable treat for cats.
Loved this tutorial? I have a bunch more over at my blog.
Step 1: Cutting the Liver
Cut the liver into 2 X 2 inch chunks, like in the second picture. Now is the time to preheat the oven to it’s lowest setting, which is usually 250F.
Step 2: Boiling the Liver
Place the liver chunks into a decent sized pot and add a generous amount of water to cover the meat. Put the poton a burner turned onto HIGH. The liver chunks should start to boil in about 10 minutes. Liver cooks really quickly, so let the liver cook at a full boil for about 5 minutes and remove the pot from the burner.Take kitchen tongs and remove the liver chunks from the water. Place them on a plate covered with some paper towels to soak up the water and to let the liver cool.
Step 3: Slicing the Liver Chunks Into Slivers
To dry the liver effectively, it must be sliced into smaller slivers. Try to cut the liver into uniform pieces so that everything dries evenly. For these chunks, 1/4″ thick pieces seemed to work well. Put the slivers on a well oiled cookie sheet and place in the preheated oven. Drying time in the oven will be approximately 1.5 to 2 hours, depending on how thick you have cut the pieces.
Step 4: Drying the Liver
After an hour check on the liver, but it will probably need more time. The liver will be done when it is no longer rubbery and snaps into pieces when you try to break it.
