Ingredients

  • 2 lb mussels (35 to 45; preferably cultivated), scrubbed well and beards removed
  • cup dry white wine
  • 2 whole hard-boiled large eggs
  • 2 tablespoons white-wine vinegar
  • ¼ teaspoon salt
  • ¼ teaspoon black pepper
  • ¼ cup extra-virgin olive oil
  • ½ cup finely chopped celery
  • ½ cup pickled cocktail onions, trimmed and finely chopped
  • 2 tablespoons chopped fresh tarragon
  • 1 garnish seaweed

Cooking Instructions

  1. 1.

    Cook mussels in wine in a 4- to 6-quart pot over moderately high heat, covered, until mussels just open wide, checking frequently after 4 minutes and transferring opened mussels to a large bowl using a slotted spoon. (Discard any unopened mussels after 8 minutes.)

  2. 2.

    Pour cooking liquid through a fine-mesh sieve into a 1- to 2-quart heavy saucepan and boil until reduced to about 3 tablespoons, about 5 minutes. Transfer to a bowl.

    Finely chop eggs, then add to reduced liquid along with vinegar, salt, and pepper. Add oil in a slow stream, whisking, then whisk in celery, onions, and tarragon. Season vinaigrette with salt and pepper.
