Step 1

Put the eggs in a small saucepot. Add cold water to cover by about 1-inch. Bring the water to a boil over medium-low heat, then turn off the heat, cover and let sit for about 12 minutes.

Step 2

Cool the eggs down in cold water, then peel and split lengthwise. Remove the yolks to a bowl and reserve the whites. Using a fork, mash the yolks with salt, pepper, to taste, and Dijon until smooth. Add the shallot, gherkins, brine and tarragon and stir to combine. If too thick, add a teaspoon more of gherkin brine liquid. Spoon into a resealable plastic bag and cut off a corner. Pipe the yolk mixture into the egg white halves. Top each half with a tarragon leaf. Arrange on a serving platter and serve.
