In a large bowl, combine okra and buttermilk; let stand for 15 minutes.
In a large Dutch oven, pour oil to a depth of 2½ inches, and heat over medium-high heat until a deep-fry thermometer registers 350°.
In a medium bowl, whisk together flour, cornmeal, seasoned salt, and cornstarch. Working in batches, drain okra from buttermilk, and dredge in flour mixture. Fry until golden brown, about 4 minutes. Let drain on paper towels.
Notes
Kitchen Tip: Fried okra can be kept warm in a 200° oven for up to 30 minutes before serving.
