01 - Place 6 large eggs in a saucepan and cover with cold water by 1 inch. Bring to a rolling boil over high heat, then immediately reduce to a gentle simmer. Cook for exactly 10 minutes for fully set yolks. Transfer eggs to an ice water bath and let cool completely for 10–15 minutes before peeling.
02 - Slice each peeled egg in half lengthwise with a sharp knife. Carefully scoop out the yolks and transfer to a mixing bowl. Place the hollowed white halves on a clean plate or cutting board.
03 - Mash the yolks thoroughly with a fork until smooth and crumbly. Add mayonnaise, Dijon mustard, white wine vinegar, cayenne pepper, and chopped chives. Season with salt and black pepper to taste. Mix until completely incorporated and creamy.
04 - Spoon or pipe the yolk mixture back into the egg white halves, mounding slightly above the edge. Smooth the tops with a small spatula or the back of a spoon for even breading.
05 - Arrange three shallow dishes in a row. Place flour in the first dish. Beat the 2 eggs in the second dish. Combine panko bread crumbs, paprika, 1/2 teaspoon salt, and 1/4 teaspoon black pepper in the third dish.
06 - Dredge each filled egg half in flour, shaking off excess. Dip into the beaten egg, allowing excess to drip off. Press firmly into the panko mixture to coat completely on all sides. Transfer breaded eggs to a baking sheet and refrigerate for 10–15 minutes to set the coating.
07 - Pour vegetable oil into a large skillet to a depth of 1 inch. Heat over medium-high heat until the temperature reaches 350°F. Use a kitchen thermometer to monitor the oil temperature accurately.
08 - Working in batches of 4–6 eggs, carefully place breaded eggs in the hot oil filling side up. Fry for 2–3 minutes until deep golden brown, turning once halfway through for even coloring. Remove with a slotted spoon and drain on paper towels.
09 - Transfer fried deviled eggs to a serving platter. Sprinkle with additional chopped chives for color. Serve immediately while crispy and warm, with optional dipping sauce on the side.
