Salt brine the steak: Set the 6 beef cube steak pieces on a wire rack over a sheet tray. Sprinkle about 1/4 teaspoon kosher salt over the top side of each piece. Refrigerate uncovered for about 2 hours.
Season the meat: Add a few dashes of Worcestershire sauce to each piece of steak to act as a binder. Season both sides with Spice That or your favorite all-purpose seasoning and a little extra black pepper. Set aside while you build your dredging station.
Set up the dredging station: In a wide-bottomed bowl, add 1½ cups all-purpose flour, for first dredge bowl. In a second bowl, whisk together 4 large eggs and 1 tablespoon hot sauce. In a third bowl, combine 1½ cups all-purpose flour, ½ cup panko breadcrumbs, 17 saltine crackers, crushed into crumbs, 1 tablespoon black pepper and ½ tablespoon salt.
Bread the steak: Working one piece at a time, coat the steak in the flour bowl, then dip in the egg mixture, then press into the final breading mixture to coat. Transfer each piece to a wire cooling rack as you go.
Let the coating set: Rest the breaded steak on the wire rack for a few minutes while the griddle heats up. This helps the coating firm up before frying.
Heat the griddle: Preheat your griddle to medium heat, about 375–400°F.
Add oil and fry: Add about 1 cup oil onto the griddle to shallow fry. Let it heat for a few seconds, then lay the steak pieces down. Use your spatula or scraper to pull extra oil back toward the steak as needed. Fry on the first side about 3-5 minutes, or until golden brown.
Flip and finish: Once the first side is deep golden brown, flip and cook the second side the same way until golden and crispy throughout, about another 3-5 minutes.
Rest and serve: Transfer the steak to a clean rack and let rest for a minute before serving hot off the griddle.
