In a large, heavy-bottomed pan, heat the vegetable oil
over medium heat until a deep-frying
thermometer inserted in the oil reaches 350 degrees F.
Prepare a baking tray lined with paper towels.
Combine the flour, cornmeal, black pepper, paprika, and garlic powder, in a shallow bowl.
Put the egg whites, and a pinch of salt into another bowl, and whisk
until the mixture is frothy
. Dip the okra in the egg whites and allow the excess egg
whites to drip off, then dip the okra into the flour mixture, shake off the excess flour, and gently drop into the preheated oil.
Fry the vegetables until golden brown, turning frequently for even color.
Transfer the fried okra to a tray, lined with paper towels to absorb the excess oil, and season with salt, to taste. Coat, and fry, and season the remaining okra. Serve with the Chipotle Sour Cream.
