01 - Place 6 eggs in a saucepan and cover with water. Bring to a boil, then reduce heat and simmer for 10 minutes. Transfer to an ice bath until completely cooled, then peel carefully.
02 - Slice eggs in half lengthwise. Gently remove yolks and set whites aside on a clean surface.
03 - Mash yolks thoroughly in a bowl. Add mayonnaise, Dijon mustard, white wine vinegar, cayenne pepper, chives, salt, and black pepper. Mix until completely smooth and creamy.
04 - Spoon or pipe the yolk mixture into the egg white halves, mounding slightly above the edges.
05 - Arrange three shallow dishes: place flour in the first, beaten eggs in the second, and mix panko with paprika, salt, and black pepper in the third.
06 - Dredge each filled egg half in flour, shaking off excess. Dip in beaten egg, then coat thoroughly with panko mixture. Place on a plate and refrigerate for 10-15 minutes to set coating.
07 - Pour 1 inch of vegetable oil into a large skillet and heat to 350°F.
08 - Fry breaded eggs in batches, filling side up, for 2-3 minutes until golden brown. Turn gently for even coloring. Remove with slotted spoon and drain on paper towels.
09 - Sprinkle with additional chopped chives and serve immediately while crispy.
