Add cubed steak to a casserole dish and pour ½ cup buttermilk over the top. Tenderize for 30 minutes in the fridge.
2 lb cube steak, 1½ cups buttermilk
Add saltines to a food processor and pulse into fine crumbs, or add to a ziplock and crush with a rolling pin.
50 saltines crackers
Prepare a dredging station with three bowls or shallow pans. Whisk together the flour, cornstarch, and salt in one bowl. Beat together the egg and the remaining 1 cup of buttermilk in another. Then mix the saltine crumbs, pepper, and paprika in the last bowl.
1½ cups buttermilk, 50 saltines crackers, 1 cup all-purpose flour, 1 tablespoon cornstarch, 1 teaspoon salt, 1 large egg, ¼ teaspoon smoked paprika, 1 teaspoon coarse black pepper
Heat 2 inches of canola oil in a frying pan to 350°F and preheat the oven to 200°F.
Prepare a baking sheet for the uncooked breaded steak, and a wire rack lined baking sheet for the cooked steak.
Remove cubed steak from the fridge. Allow excess buttermilk to drip off the steak, then dip it in the flour. Press flour into the steak and evenly coat both sides. Next, dip each side of the steak into the buttermilk and egg mixture. Then, place it in the bowl with the saltine crumbs. Press the cracker crust into the steak and thoroughly cover each side with the crumbs. Place onto a baking sheet and store in the fridge as you work.
Fry the steak in the order they were put into the fridge so the one in the cold the longest is the first to be fried. Keep the uncooked steak in the fridge as you are frying. The cold helps the steak to hold its shape and helps the breading to stick better while frying.
Once the first steak is done frying, place it onto a wire rack lined baking sheet. Keep the baking sheet in the oven as you work.
