01 - Place 6 large eggs in a saucepan and cover with water. Bring to a rolling boil, then reduce heat to medium-low and simmer for exactly 10 minutes. Immediately transfer to an ice bath and let cool completely before peeling.
02 - Slice peeled eggs in half lengthwise. Carefully scoop out yolks and place them in a mixing bowl. Set aside the hollowed egg white halves on a clean surface.
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 generously with salt and black pepper. Mix until completely smooth and creamy.
04 - Spoon or pipe the yolk mixture into the reserved egg white halves, mounding slightly above the edge. Ensure even distribution among all 12 halves.
05 - Arrange three shallow dishes: place flour in the first, beat 2 eggs in the second, and combine panko crumbs with paprika, salt, and black pepper in the third.
06 - Working one at a time, dredge each filled egg half in flour (shake off excess), dip in beaten egg, then press firmly into panko mixture to coat completely. Transfer to a plate 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 it reaches 350°F. Use a kitchen thermometer to verify temperature.
08 - Fry breaded eggs in batches, filling side up, for 2–3 minutes until deep golden brown. Turn gently halfway through for even coloring. Remove with a slotted spoon and drain on paper towels.
09 - Sprinkle with additional fresh chives. Serve immediately while crispy and warm. For best texture, avoid holding longer than 15 minutes.
