In a shallow bowl, whisk together the egg and buttermilk. Add the okra to the bowl and toss to coat. Set aside for 10 minutes.
1 large egg, ¼ cup buttermilk, 1 pound okra*
In a Dutch oven, heat 1 inch of oil to 375°F. Line a plate with paper towels.
Vegetable oil
While the oil is heating, whisk the flour, cornmeal, salt, and pepper in another shallow bowl.
½ cup all-purpose flour, ½ cup cornmeal**, ½ teaspoon kosher salt, ¼ teaspoon ground black pepper
Remove the okra from the egg mixture using a slotted spoon or tongs, letting any excess drain off. Place it into the flour/cornmeal mixture and toss to coat. After coating, shake off any excess flour. This helps to prevent the formation of a thick, doughy crust.
Fry the okra in batches until golden on all sides, about 2-3 minutes. Make sure not to overcrowd the pan. Overcrowding can cause the oil temperature to drop, resulting in soggy okra.
Place the okra on the paper towel-lined plate to drain excess oil and maintain its crispy texture. Season with another pinch of salt.
Fried okra is best served right after frying when it's still hot and crispy. If you need to keep it warm, place it in a 200°F oven.
