I have never used a food
dehydrator, but have always smoked my jerky. I also usually do about 5 pounds of London Cut at a time. That being said, with the soy sauces, and other types of liquid seasonings I use to make my marinades there is usually a large amount of salt content. Most of the time I use 1 to 2 tablespoons of salt (Kosher). Depending on the amount of time that I choose to marinade I use this as my basis for how much salt I will be using. I go with 1/2 Kosher, and 1/2 Morton's cure. I do not cure first, I just add it to my marinade. I base the cure penetration at 1/4 inch every 12 hours, normally using 1 tablespoon/ 1 tablespoon. If I want to marinade longer I decrease the amount of salts. The amount is also effected by how thick my slices are. I usually cut my slices at 1/4 inch. Like I stated, I use my smoker and not a
dehydrator, but this has never disappointed me or my taste testers. Dehydrators may change things, but I would assume cure penetration in the marinade would be more effective than just coating the meat then washing it off. I hope this helps.
