In a large bowl, combine cornmeal, flour, baking powder, salt, pepper, and garlic powder. Stir to mix.

Add the chopped okra, onion, and optional jalapeño to the dry mixture and stir until well coated.

In a separate bowl, whisk together the egg, buttermilk, and melted butter. Add to the okra mixture and stir to form a thick batter.

Heat about 1/4 inch of vegetable oil in a skillet over medium heat.

Scoop about 2 tablespoons of batter for each patty into the skillet. Flatten slightly and cook for 2–3 minutes per side, or until golden brown.

Remove patties and drain on paper towels. Serve warm with your favorite dipping sauce.
