Combine the olive oil, sherry vinegar, basil, shallots, tomatoes, lemon rind, chives, and tarragon. Season with salt and pepper to taste. Let marinate overnight, unrefrigerated.
Cut carrots, leek and celery into julienne. Cook them in 1 cup strained court bouillon until tender but still crisp. Drain and reserve.
Wrap each salmon fillet in foil and poach in court bouillon for approximately 5 minutes.
To check the degree of doneness, remove 1 package from the liquid and unwrap. The center should still be slightly pink.
