Well, I was surprised Tuesday by a call from my favorite butcher. They were calling their customers to offer a deal . . . Beef Flank steak for 90 cents a pound if it was picked up between 7:30am and 10am the next day, must be ordered by phone. It turns out that a catering company had ordered some huge amount, paid for half, then backed out. It had been delivered and the butcher decided to just get his money back out of it because there wasn't room to MOVE in his chiller. So . . . on an impulse, I ordered 100lbs.
I vac sealed 32 lbs for later use in Fajitas (pounded the bejeebers out of it, vac sealed it in portions suitable for our family, 7 meals).
The rest I sliced for Jerky. We were almost out anyway . . . so far, I've made four recipes and they're turning out really yummy. I've never made this much at once before, so I had to "scale up" my methods.
I've never made this much jerky before. I did NOT look forward to slicing all that meat by hand. So, I set out to figure out a way to make it easier. Here's what worked.
I used an electric knife to slice partially frozen meat just a few degrees off the grain! As far as I'm concerned, this is the TRICK to making good jerky. If you slice along the grain, it's just too hard to bite off, If you slice across the grain, it just falls apart, BUT if you slice a few degrees off the grain . . . perfection. Essentially, the "strings" of meat end up long enough to hold together and short enough that you can tear it off without breaking your jaw.
My method of drying Jerky is simple . . . you need a lot of air movement, just a tiny bit of heat, and a way to keep the critters away. A cardboard box, box fan. Inside, I put aluminum foil on the bottom, then stacked up the grill racks, and the racks DH made with some leftover moldings and fiberglass screen material (he used little chunks of the wood to make standoffs so they'd stack with a gap. This allowed me to dry about 25 lbs of meat at once and it worked great.

I sit the box in our sunroom, but honestly, if your house is air conditioned it's OK. This much airflow will dry the meat really fast. Mine was all dry in about 12 hours and it turned out just perfect.
In half the box, I used racks I already have (from the oven, cooling racks, and the smoker), the other half has the nice neat stack that DH built.
