01 - Lay the green tomato slices on a wire rack or paper towels. Sprinkle both sides with 1 teaspoon of salt and let sit for 10 minutes to draw out excess moisture. Pat dry with paper towels.
02 - Prepare a breading station: Place 1 cup all-purpose flour in one shallow bowl. In a second bowl, whisk 2 large eggs and 1/4 cup whole milk together. In a third bowl, combine 1 cup cornmeal, 1/2 cup breadcrumbs (preferably panko), 1/2 teaspoon garlic powder, 1/2 teaspoon paprika, and 1/2 teaspoon freshly ground black pepper.
03 - Dip each tomato slice first in the flour, ensuring full coverage. Then, dip in the egg mixture, allowing excess to drip off. Finally, coat thoroughly in the cornmeal mixture, pressing gently to adhere the coating.
04 - In a large skillet, pour vegetable oil to a depth of 1/2 inch (approximately 1 to 2 cups, depending on skillet size) and heat over medium heat until it reaches approximately 350°F (175°C) and shimmers slightly.
05 - Fry the tomato slices in batches to avoid overcrowding the pan. Cook each side for 2–3 minutes, or until golden brown and crisp. Transfer the fried tomatoes to a paper towel-lined plate to drain any excess oil.
06 - For the remoulade sauce, 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 parsley, 1 teaspoon smoked paprika, and 1 small finely minced garlic clove in a small bowl until smooth. Taste and adjust seasoning with salt and pepper as needed.
07 - Serve the fried green tomatoes hot, accompanied by the remoulade sauce on the side for dipping.
