Begin by blending the flour, cracker crumbs, salt, black pepper, and cayenne pepper in a bowl.
Pour the buttermilk into another bowl.
Dip each cube steak in the buttermilk, ensuring it is fully covered.
Coat the steak in your flour and cracker crumb mix.
Press the mixture onto the steak to guarantee adherence.
Heat oil in a skillet over medium heat.
Once hot, place the coated steaks into the pan gently.
Cook each steak for about 5 minutes on each side, or until browned and crispy.
Once cooked, move the steaks to a plate lined with paper towels to soak up any excess oil.
