MUSTARD SAUCE FOR FISH RECIPES

Steps:

• Preheat the oven to 375 degrees F. Line a large baking sheet with a nonstick silicone liner, and lay the salmon, skin side down, on top. Set aside.
• Combine the mayonnaise, mustard, honey and chives in a medium bowl and stir to thoroughly combine. Reserve half of the sauce. Spoon the remaining sauce over the fish, spreading it evenly all over the top and sides of each fillet. Sprinkle with salt and pepper.
• Roast just until the fish is opaque in the center, 7 minutes. Increase the oven to broil. Broil the fish for 6 to 7 minutes, but keep your eye on it to avoid overcooking. Garnish with chives and serve with the reserved sauce.

Steps:

• Sprinkle the chicken with salt and pepper. Heat the oil in a heavy large skillet over high heat. Add the chicken and cook just until brown, about 4 minutes per side. Transfer the chicken to a plate and cool slightly.
• While the chicken cools, melt 2 tablespoons of butter to the same skillet over medium-high heat, then add the onion and saute until tender, about 2 minutes. Add the mushrooms and garlic and saute until the mushrooms are tender and the juices evaporate, about 12 minutes. Add the wine and simmer until it is reduced by half, about 4 minutes. Stir in the mascarpone and mustard. Cut the chicken breasts crosswise into 1/3-inch-thick slices. Return the chicken and any accumulated juices to the skillet. Simmer, uncovered, over medium-low heat until the chicken is just cooked through and the sauce thickens slightly, about 2 minutes. Stir in the chopped parsley. Season the sauce, to taste, with salt and pepper.
• Meanwhile, bring a large pot of salted water to a boil. Add the fettuccine and cook until al dente, stirring occasionally, about 8 minutes. Drain. Toss the fettuccine with 3 tablespoons of butter and season, to taste, with salt and pepper. Swirl the fettuccine onto serving plates. Spoon the chicken mixture over top. Garnish with parsley sprigs and serve.
