I went veg and missed jerky, so I tried this out and it actually turned out really well.
(It really does taste better than it looks.)
Step 1: Ingredients
Vinegar, either malt or apple cider
Salt and Pepper
Step 2: Drain, Cut and Marinate
Drain the tofu by wrapping the block in cloth or paper towels then place between two plates and put some weight on top ( a bag of flour or something about that weight) and let it sit for about 15-20 min. Cut the tofu into strips, then put them in a zip-top bag. Then add the other ingredients, I just eyeball it, but, I would say about a table spoon of all the wet ingredients and 1/2 of the dry. Then close the bag squeezing out as much of the air as possible. Then put it in the fridge overnight.
Step 3: Prepping for the Oven
I don't have a dehydrator so I used the oven, if you have a dehydrator use that. Set the oven to 200, this takes a few hours so there's no reason to pre-heat. Put some parchment paper on a baking sheet and then put the tofu on top of that.
Step 4: Cooking/Drying
Put it in the oven and let it cook/dry for 4-6 hours flipping every hour. The time will vary depending on the humidity.
Step 5: Finishing
When it's done it should look like it does below. I know it looks burnt and not very tasty, it's not burnt and it is tasty! You can change the ingredients to match your own tastes I just listed how I did it. Enjoy!
