Step 1: Hard Boil the Eggs
Place the eggs in a single layer at the bottom of a large pot.
Cover with cold water, about 1 inch above the eggs.
Bring to a boil over medium-high heat. Once boiling, cover and remove from heat.
Let sit for 12 minutes, then transfer the eggs to an ice bath to cool completely.

Step 2: Peel and Prepare the Eggs
Once the eggs are cool, gently peel them under running water.
Pat dry with a paper towel.
Slice each egg in half lengthwise and carefully remove the yolks, placing them into a mixing bowl.

Step 3: Make the Filling
Mash the yolks with a fork until they are fine and crumbly.
Add mayonnaise, sour cream, Dijon mustard, sweet pickle relish, vinegar, sugar, salt, and pepper.
Mix until completely smooth and creamy. You can also use a hand mixer for an ultra-silky texture.

Step 4: Fill the Egg Whites
Spoon or pipe the filling evenly into each egg white half.
For a fancy presentation, use a piping bag fitted with a star tip.

Step 5: Garnish and Serve
Lightly dust the tops with paprika for color and flavor.
Sprinkle chopped fresh chives or parsley over the eggs.
Add optional toppings like crispy fried onions or a tiny piece of cooked beef bacon for an extra flair.
