This was my first time. I wanted a snack for mountaineering so salty and carbs are good.
For 1 kg of eye round I started with this recipe.
1 cup (packed) dark brown sugar
1 cup soy sauce
3 tablespoons Worcestershire sauce
1 tablespoon smoked paprika
1 teaspoon unseasoned meat tenderizer (see note)
1 teaspoon freshly ground black pepper
1 teaspoon red pepper flakes
1 teaspoon onion powder
½ teaspoon garlic powder
My brown sugar was clumped up so I used 1/2 cup of black strap molasses. That worked out well.
The eye round from Costco is a nice lean chunk of meat at a reasonable price. It's easy to see the grain and cut against it. Even though I did not use meat tenderizer it's easy to bite from it.
I went with the dehydrator instructions to cook it for 6 hours at 165f. That was a bit too long. Next time I will try to see how it is at 5hrs. Overall I'm really happy with how it came out.
