Mussels with Tarragon Celery Vinaigrette

Directions

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.

3. 3.

   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.

4. 4.

   Remove mussels from shells and reserve 1 half shell from each mussel. Stir mussels (but not shells) into vinaigrette and marinate, covered and chilled, at least 1 hour. Rinse and dry reserved mussel shells, then chill in a sealed plastic bag until ready to use.

5. 5.

   Arrange shells on a large platter lined with seaweed and spoon a mussel with some vinaigrette into each.

6. 6.
