Poached Halibut with Eberhard

Bring a large pot of salted water to a boil. Prepare an ice-water bath; set aside. Blanch carrots in boiling water until tender. Transfer to ice-water bath to cool. Drain well, and set aside. Repeat with celery, onion, and leek.

Season fish with salt and pepper. Place tarragon-vegetable broth in a straight-sided skillet just large enough to hold fillets in one layer. Add fish. Place over medium heat, and bring to a boil. Turn fish fillets, and cook 2 minutes more. Remove fish to shallow bowls, and keep warm.

Add vegetables to broth, and reheat. Add chopped tarragon, and swirl in the butter. Taste broth, and adjust for seasoning. Ladle broth and vegetables over halibut. Garnish with sprigs of tarragon. Serve immediately.
