How to make Salmon with Lemon-Pepper Sauce and Watercress-Herb Salad

Whisk crème fraîche, 1 tablespoon lemon juice, and 1/2 teaspoons lemon peel in small bowl. Season with salt and generous amount of pepper.

Whisk honey, 1 tablespoon olive oil, shallot, 2 tablespoons lemon juice, and remaining 1/2 teaspoons lemon peel in 11x7x2-inch glass baking dish. Add salmon fillets and turn to coat. Cover and chill at least 15 minutes and up to 1 hour, turning salmon fillets occasionally. Position rack in top third of oven and preheat to 204°C. Line large baking sheet with foil and brush with olive oil. Transfer salmon fillets, with some marinade still clinging, to rimmed baking sheet. Roast until salmon is just opaque in centre, about 14 minutes.

Meanwhile, toss watercress leaves and sprigs, dill sprigs, tarragon leaves, remaining 2 teaspoons lemon juice, and remaining 2 teaspoons olive oil in medium bowl. Season to taste with fleur de sel and pepper.

Place 1 salmon fillet on each of 6 plates. Top with watercress salad. Drizzle with lemon-pepper sauce and garnish with lemon wedges. Serve, passing additional sauce alongside.
