I'm in the process of making some last night after reading this blog:
Son of Grok Blog Archive Recipe: The SoG Jerky Method
I bought 2 pounds of 1/4 inch thick top flank at my local meat store for 6.99/lb. I then cut the slabs into strips and soaked them in a simple marinade recommended here: soy sauce, teriyaki sauce and Montreal streak spice. I marinated the strips for 4.5 hours.
I then realized I didn't have any racks, so I just used the racks from my oven and put them on my kitchen counter with tin foil underneath. Next, I laid all the strips on the racks and set my fan up directly in front of the two racks. Before I left the house today I turned my heat down to 50 F. When I get home tonight at 11 pm they will have been drying for 17 hours and should be ready.
I'm personally sick of buying 3 oz. of jerky from the gas station for $6.50. I just made about 1.3 lbs (after drying) for $20 bucks, thats about half the gas station price. Plus there is less salt, and I get a certain satisfaction from making it.
