Dry the Meat:
Preheat the oven to 200°. Set a large wire rack on each of 3 large rimmed baking sheets. Remove the beef from the marinade and pat dry with paper towels. Arrange the beef on the racks, leaving 1/4 inch between slices. Sprinkle with coarsely ground black pepper. Bake for about 4 hours, until the jerky is firm and almost completely dry, but still chewy. Let cool completely on the racks before serving.
