Start by hard-boiling your eggs. Place the eggs in a pot, cover them with water, and bring to a boil. Once boiling, cover the pot and remove it from heat. Allow the eggs to sit for about 9-12 minutes. Afterward, transfer them to ice water to cool before peeling.
Once the eggs are peeled, slice them in half lengthwise and gently remove the yolks, placing them in a mixing bowl.
To the bowl with the yolks, add the chopped fresh jalapeño, pickled jalapeño brine, mayonnaise, dill, lemon juice, mustard, smoked paprika, salt, and pepper. Mash everything together with a fork until it reaches a smooth consistency.
Taste the filling and adjust the seasoning as necessary. If you like it spicier, feel free to add more fresh jalapeño or brine.
Using a spoon or a piping bag, fill the egg white halves with the yolk mixture. If you’re using a piping bag, snip the end for a neater presentation.
Top each egg with a slice of jalapeño for garnish. Sprinkle additional smoked paprika over the top, if desired, for a pop of color. Serve immediately or refrigerate until ready to serve.
