Ground Beef Jerky

Directions

1. 1
   Stir salt, chili powder, garlic powder, onion powder, ginger, black pepper, and cayenne pepper together in a large bowl; add ground beef and mix well.
2. 2
   Pass beef mixture through a meat grinder set with the finest blade.
3. 3
   Preheat oven to 250 degrees F (120 degrees C). Place wire-racks onto baking sheets.
4. 4
   Place 1/2 ground beef mixture between two sheets of heavy plastic on a solid, level surface. Firmly roll beef mixture to a thickness of 1/8 inch. Remove the top layer of plastic wrap, invert beef mixture onto prepared baking sheet, and remove the bottom layer of plastic wrap. Repeat for remaining beef mixture.
5. 5
   Bake beef mixture in the preheated oven with the oven door slightly ajar for 2 1/2 hours. Rotate the baking sheet. Bake until jerky is cooked through, another 3 hours. Remove jerky from oven and cut into strips while warm.
