In a large mixing bowl, whisk together the cornmeal, flour, baking powder, baking soda, salt, and sugar.
In a separate bowl, whisk the buttermilk and egg until well combined.
Pour the wet ingredients into the dry and mix until just combined.
Fold in the chopped okra, onion, and herbs. Let the batter rest for 10 minutes.
Heat about 2 inches of vegetable oil in a heavy-bottomed skillet to 350°F (175°C).
Using a cookie scoop or tablespoon, drop small mounds of batter into the hot oil.
Fry in batches for 2–3 minutes per side or until golden brown and crispy.
Remove with a slotted spoon and drain on paper towels or a wire rack.
Serve warm with your favorite dipping sauce or alongside your favorite Southern dishes.
