Carefully peel the hard-boiled eggs and slice them in half lengthwise. Gently remove the yolks and place them in a small bowl, arranging the whites on a serving platter.

Mash the egg yolks thoroughly with a fork until they are finely crumbled. Add mayonnaise, Dijon mustard, white vinegar, salt, and pepper to the mashed yolks, mixing until smooth and creamy.

Spoon or pipe the yolk mixture back into the egg white halves. Garnish each deviled egg with a sprinkle of paprika for color and flavor.
