Tarragon Walnut Brown Butter Sauce Recipes

Steps:

• Pat the scallops dry and sprinkle with salt and pepper.
• Heat 1 tablespoon butter in a 12-inch nonstick skillet over medium-high heat until the foam subsides, then sear the scallops, turning once, until golden brown and just cooked through, about 5 minutes total. Transfer to a platter.
• Add the shallot, wine, and vinegar to the skillet and boil, scraping up any brown bits, until reduced to 2 tablespoons. Add the juices from the platter and if necessary boil until the liquid is reduced to about 1/4 cup. Reduce the heat to low and add 3 tablespoons butter, stirring until almost melted, then add the remaining 3 tablespoons butter and swirl until incorporated and sauce has a creamy consistency. Stir in the tarragon and salt to taste; pour sauce over scallops.

Steps:

• Preheat oven to 350°F. Spread hazelnuts in a single layer on a rimmed baking sheet and toast, stirring occasionally, until golden, 8-10 minutes. Coarsely chop; set aside.
• Reduce oven temperature to 300°F. Scatter tarragon sprigs on a large rimmed baking sheet. Place halibut on top, drizzle with 2 tablespoons oil, and season with salt and pepper. Roast until halibut is just opaque in the center, 20-30 minutes, depending on thickness of fish.
• Meanwhile, melt butter in a small saucepan over medium-high heat. Cook, stirring often, until butter foams, then browns (don't let it burn), about 5 minutes. Remove from heat; let brown butter cool slightly. Stir in lemon juice, hazelnuts, and remaining 2 tablespoons oil; season with salt and pepper.
• Serve fish with hazelnut brown butter sauce and lemon halves.
