SOUR CREAM MUSTARD SAUCE RECIPES

Steps:

• Whisk sour cream, dill, onion and mustard in small bowl to blend. Season sauce to taste with salt and pepper. Let stand at room temperature 1 hour.
• Preheat oven to 400°F. Lightly oil baking sheet. Place salmon, skin side down, on prepared sheet. Sprinkle with garlic, salt and pepper; spread with 1/3 cup sauce. Bake salmon until just opaque in center, about 20 minutes. Serve with remaining sauce.

Steps:

• Season roast all over with 2 Tbsp. steak seasoning. Transfer to a wire rack set inside a rimmed baking sheet and let sit at room temperature 1 hour.
• Preheat oven to 225°F. Roast beef until an instant-read thermometer inserted into the center registers 120°F, 3 1/2–4 hours (start checking every 5–10 minutes after 3 1/2 hours). Tent with foil and let sit at least 30 minutes and up to 1 hour. Increase oven temperature to 500°F.
• Meanwhile, whisk sour cream, horseradish, pepper, salt, and 1/4 cup mustard in a small bowl; set aside.
• Remove string from roast; discard. Stir butter and remaining 1/4 cup mustard in another small bowl. Using a pastry brush, thickly coat roast with mustard-butter sauce. Coat with remaining 2 Tbsp. steak seasoning. Roast beef until a brown crust forms, 5-10 minutes. Transfer to a cutting board and carve. Serve with sour cream sauce alongside.
• Sour cream sauce can be made 1 day ahead. Transfer to an airtight container and chill.
