Mix all ingredients for the marinade.
⅔ cup soy sauce, ⅔ cup Worcestershire sauce, 1 teaspoon liquid smoke, 2 teaspoons freshly ground pepper, 1 teaspoon onion powder, 1 teaspoon garlic powder, 1 teaspoon cayenne pepper, 1 tablespoon paprika, 1 tablespoon brown sugar, 2 tablespoons pineapple juice, *For spicy version, simply replace 1 teaspoon liquid smoke with 1 tablespoon hot pepper flakes.
Cut the slightly frozen meat against the grain in even ¼-inch slices.
2 pounds top round London broil
Mix the meat and marinade (after mixing it in a bowl, transfer it to a gallon ziploc bag and squeeze out most of the air before closing it. This will help marinate the meat evenly) and refrigerate for at least four hours and up to overnight.
Shake or dab off any excess marinade and lay the meat strips evenly on the trays of the food dehydrator.
Set the temperature to 160℉.
Rotate the trays approximately every hour (put the top tray on the bottom) to ensure even drying. But I’m not even sure if that’s necessary because of the built-in fan.
Start checking after about 3-½ hours for doneness. When bending the meat strip, it should crack but not break.
