01 - Lay the green tomato slices on a wire rack or paper towels. Sprinkle both sides with 1 teaspoon kosher salt and let them sit for 10 minutes to draw out excess moisture. Pat dry thoroughly with paper towels before proceeding.
02 - Prepare a three-station breading assembly. In the first shallow bowl, place 1 cup all-purpose flour. In the second shallow bowl, whisk together 2 large eggs and 1/4 cup whole milk until well combined. In the third shallow bowl, combine 1 cup cornmeal, 1/2 cup panko breadcrumbs, 1/2 teaspoon garlic powder, 1/2 teaspoon paprika, and 1/2 teaspoon freshly ground black pepper.
03 - Take each prepared tomato slice and dredge it first in the all-purpose flour, ensuring it's lightly coated and shaking off any excess. Next, dip the floured slice into the egg mixture, allowing any excess to drip back into the bowl. Finally, thoroughly coat the tomato slice in the cornmeal mixture, pressing gently to ensure the breading adheres completely.
04 - In a large, heavy-bottomed skillet, pour vegetable oil to a depth of approximately 1/2 inch. Heat the oil over medium heat until it shimmers and reaches a temperature of about 350°F (175°C).
05 - Carefully place the breaded tomato slices into the hot oil in batches, ensuring not to overcrowd the skillet. Fry for 2 to 3 minutes per side, or until they achieve a golden brown color and a crisp texture. Transfer the fried tomatoes to a paper towel-lined plate to drain any excess oil.
06 - In a small mixing bowl, whisk together 1/2 cup mayonnaise, 1 tablespoon Dijon mustard, 1 tablespoon whole grain mustard, 1 tablespoon prepared horseradish, 1 tablespoon lemon juice, 1 teaspoon hot sauce, 1 teaspoon finely chopped capers, 1 tablespoon finely chopped fresh parsley, 1 teaspoon smoked paprika, and 1 small finely minced garlic clove until the sauce is smooth and thoroughly combined. Taste and adjust the seasoning with salt and pepper as desired.
07 - Serve the crispy fried green tomatoes immediately while hot, accompanied by the zesty remoulade sauce on the side for dipping.
