Wash the okra thoroughly and slice it into 1/2-inch pieces.
In a bowl, mix cornmeal, flour, salt, black pepper, and cayenne pepper.
Pour buttermilk into another bowl.
Dip each okra piece into the buttermilk.
Transfer the okra to the cornmeal mixture, ensuring it is evenly coated.
Heat oil in a deep skillet or fryer to 350°F (175°C).
Add the coated okra to the hot oil in batches.
Fry for 3-4 minutes until golden brown and crispy.
Remove the okra with a slotted spoon and drain on paper towels.
Season with additional salt if desired and serve hot.
