--------  ------------  --------------------------------
   5      pounds        beef -- (roast)
     1/4  cup           soy sauce
   1      tablespoon    Worcestershire sauce
   1      tablespoon    garlic powder
   1      tablespoon    onion powder
   1      tablespoon    black pepper -- preferably cracked
                        red pepper flakes -- optional
   1      tablespoon    liquid smoke

Preparation:

I make Jerky by buying about 5+ lbs of beef. Usually a roast. I then remove the fat. Place the strips of meat into marinade and let soak for about 24 hours. Remove from marinade and allow to air dry for at least one hour. If you have a meat smoker then omit the liquid smoke and smoke meat at a low temperature.
