I've got a big old bowl of freshly cut eye of round from my local butcher marinading in the fridge right now. Tomorrow it'll go in the dehydrator (I'm lucky enough to have one built into my oven. I'm also very lucky to have a local butcher. Sadly not something most people have access to).
My current marinade is as follows:
¼ cup dark soy
¼ cup light soy
¼ cup water
2tbsp maple syrup
2tbsp worcestershire sauce
1tsp liquid smoke
LOTS of cracked black pepper
Optionally, add red pepper flake for a little spice. You can also up the amount of worcestershire if you like.
For my next batch I want to try adding a little fish sauce and MSG to really up the umami.
Also, I really like how making your own jerky allows you to control the grain pattern. I don't mind a little chew to mine, but my wife likes it to come apart nice and easy so for her I cut across the grain. I have a vacuum sealer that I got on clearance, so I'll batch up little packets of jerky for her to take into the field. It's so much better than the jerky she gets in her issued rations.
Sadly, finding the time and energy to do stuff like this can be a challenge. I'm fortunate in that I work from home, so I can throw this stuff in the oven before my day starts and then just pull it when it's done.
I've experimented with fish sauce before, just be real careful because even mixed into a marinade, it's so strong and distinctive then you can easily pick it out and after a couple tablespoons it'll completely overwhelm every other flavor.
I'll also say get the higher quality fish sauce, it really makes a difference.
The cheaper fish sauces do not play well with other flavors.
I don't like the liquid smoke myself, that usually turns my batches into Walmart jerky territory.
but I only have ever used q couple kinds and hated them, so I'm sure out of the billion types of liquid smoke there are a couple that are inoffensive.
and there's always personal taste.
what is liquid smoke? is it actual bits of dust?
yep, it's little bits of smoke mixed and condensed into a liquid.
have fun, I hope you have more free time, I agree it's a lot of fun to make the jerky to specification.
Old Trapper is decent jerky, but otherwise yeah. Jack Links is practically eating plastic, after trying good homemade jerky don't know how I used to eat it.
For anyone looking for a cheap home made jerky method that can be done in regular bog standard oven, try this pork teriyaki jerky method. It's super simple, and requires no equipment.
Edit: Also, keep that bit about pork tenderloin to yourselves OK? Definitely don't let anyone know that it's a ridiculously cheap cut that you can use to make an absolutely delicious Pork Wellington (definitely don't look up Alton Brown's recipe for it). And certainly don't let anyone know that if you put it in a sous vide with a little olive oil in the bag, it comes out as one of the juciest, most tender cuts of meat you've ever eaten in your life, for less than the price of the cheapest, toughest shoe-leather steaks they sell at the grocery store. Everyone is sleeping on this incredible cut of meat, and I would very much like to keep it that way.
I like Krave jerky. Lately I've been eating from these smaller bags, but I don't remember the brand name. All the fancy homemade stuff people are talking about sounds really good though.
