Fortunately, the wonderful Martin attends festivals and shows people how to make their own, I have been to such an event and can pass on the knowledge. Although it should be noted that it doesn't contain any more protein than before its dried, its just that you cut off the fat and obviously remove all the water. Buts its good for preserving meat for rations when travelling, hiking or working at festivals. I also use it so I can buy meat cheap when its on offer and not have to find room in the freezer for it.
You can only do this with dark meat, not pork, poultry etc. Any cut will do but it need to be relatively fat free, fat in chuncks you can cut off is fine.
Cut of every bit of fat
Slice meat really thin
Rub in salt and seasoning, this is only for flavouring, you only need a small amount of salt, similar to what you'd put on a meal. I use Cayenne as seasoning.
Lay on a metal grid, I use cooling trays.
Put in the oven with the oven on as low as possible and leave a slight gap in the door, just for the moisture to get out.
Takes around 4 hours but may be more. You have to make sure its totally dry because its the lack of moisture that stops it going off.
Seal in plastic food bags with as much of the air squeezed out as possible
Incidentally the traditional way of drying is over charcoal but I'm guessing you don't have anywhere you can build a charcoal fire. I believe Martin does all his over charcoal so it gets a better taste. The French for charcoal is what gives it the term "jerky" the same applies to Jamaican "Jerk" chicken, which is a very different product.
If anyone's going on any expeditions etc. Martins dried meats are very useful for that, they also do dried sheets of fruit puree and dried sausages.
