Step 1: Place the eggs in a single layer in a saucepan and cover with enough water so that there is at least an inch of water above the eggs.
Step 2: Bring the water to a rolling boil over high heat. Once boiling, immediately remove the pan from the heat and cover it with a lid.
Step 3: Let the eggs sit in the hot water for 12 minutes. Prepare an ice bath in a medium bowl while you wait.
Step 4: Transfer the eggs to the ice bath using a slotted spoon and let them cool for at least 10 minutes before peeling.
Step 5: Gently peel the eggs and slice them in half lengthwise. Carefully remove the yolks and place them in a small bowl.
Step 6: Mash the yolks with a fork or push through a sieve until smooth. Stir in the mayonnaise, mustard, vinegar, salt, and pepper until well combined.
Step 7: Use a spoon or a piping bag to fill the egg white centers with the yolk mixture. Sprinkle with paprika and chives before serving.
