Cut steaks 3/4-inch thick. Pound the steaks with meat tenderizing hammer until about 1/4-inch thick. Season with salt and pepper, to taste, and rub on other spices if you have them.
Start heating beef tallow or grease in Dutch oven. Be sure you have enough grease in the pan to cover the steaks (at least 1-inch.) Put the buttermilk in bowl and put the flour on a plate. Wet the steaks in buttermilk and then drag through flour making sure both sides have flour on them. If a thicker crust is wanted, then repeat this procedure again. When grease just begins to smoke, then you are ready to drop in a steak and cook. Cook steak until golden brown on both sides turning steak in grease, if needed. Repeat until all steaks are cooked.
