Mussels with Tarragon Celery Vinaigrette

This elegant dish of mussels with tarragon and celery vinaigrette offers a fresh, sophisticated twist on classic seafood. The mussels are gently steamed in white wine before being marinated in a vibrant, herb-flecked dressing. The addition of finely chopped hard-boiled egg provides a rich texture that beautifully balances the crunch of celery and the aniseed notes of fresh tarragon. It is a light yet deeply flavourful way to enjoy fresh shellfish during the warmer months.

As a naturally dairy-free starter, this recipe is ideal for dinner parties or as part of a refined seafood platter. Preparing the mussels in advance allows the flavours to develop, making it a stress-free option for entertaining. Serve the marinated mussels back in their shells on a bed of seaweed for a professional, restaurant-style presentation that is sure to impress your guests.

How to make Mussels with Tarragon Celery Vinaigrette

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.)

Pour cooking liquid through a fine-mesh sieve into a 1- to 2-quart heavy saucepan and boil until reduced to about 45ml , 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.

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.

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