1) Heat oil in a large, heavy-bottomed skillet to 176 degrees C. (You may not need to use this much oil; do not fill the pan more than halfway up the sides with oil.)
2) In a medium bowl, combine cornmeal, flour, house seasoning, and cayenne pepper. Dip okra in buttermilk and then dredge in cornmeal-flour mixture to coat well. Carefully add okra to the hot oil, in batches as needed, and cook until golden brown. Remove from oil, drain on paper towels, and then serve immediately.
