Ingredients
6 to 8 stems fresh tarragon, leaves reserved for vinaigrette
4 sprigs fresh thyme
2 bay leaves
1 teaspoon whole black peppercorns
1 cup sherry
1 celery stalk, roughly chopped
1/2 white onion, coarsely chopped
2 boneless, skinless chicken breasts, split in half
Coarse salt and freshly ground pepper
Lemon Vinaigrette to Make 3/4 Cup
Preparation
Make a bouquet garni: Tie tarragon stems, thyme, bay leaves, and peppercorns in a small square of cheesecloth. Place bouquet garni, sherry, celery, onion, and 5 cups water in a medium pot, and bring to a boil over high heat. Reduce heat, and let simmer for 5 minutes.
Season chicken breasts on both sides with salt and pepper. Add to the gently simmering liquid, and cook until firm and juices run clear when pierced with a two-pronged fork, 10 to 12 minutes.
Remove chicken from poaching liquid, and arrange on serving plates. Drizzle with lemon vinaigrette.
