01 - In a shallow bowl, combine all dry ingredients: flour, panko, cornmeal, baking powder, salt, pepper, paprika, garlic powder, and onion powder. Mix thoroughly.
02 - In a separate shallow bowl, whisk together eggs and milk until smooth and fully blended.
03 - Pat food dry with paper towels. Dredge each piece in the dry mixture, shaking off excess. Dip into egg mixture, allowing excess to drip off. Press into the dry mixture again for an even, thick coating.
04 - Cook the coated item by frying, baking, or air-frying according to your main preparation method.
