Instructions
Slice the partially frozen beef into long strips about 1/8 of an inch thick. Mix all the other ingredients together, except for the cayenne.
Place the beef in the marinade and let it sit, refrigerated, for at least 6 hours. After the beef has marinated, wipe off the excess liquid and pieces of minced garlic and place on foil-lined sheets with no overlap. Sprinkle meat with cayenne pepper.
Cook in the oven at 175° F for 3 hours and then turn over strips. Cook for another 2-3 hours or until it has a dry and leathery texture. (You don’t want it so brittle that it snaps.
