How to make Pork Medallions with Mustard-Chive Sauce

Melt 1 tablespoon butter with 1 tablespoon oil in large skillet over medium-high heat. Add leeks and cook until beginning to turn golden, stirring frequently, about 5 minutes. Stir in broth, wine, and garlic. Boil until mixture is reduced to 400ml , about 4 minutes. Whisk in crème fraîche and mustard; set aside. (Sauce can be made 2 hours ahead. Let stand at room temperature.) Melt 1 tablespoon butter with 1 tablespoon oil in another large skillet over medium-high heat. Sprinkle pork with salt and pepper. Sauté until browned and cooked, about 5 minutes per side. Transfer pork to platter. Add sauce to skillet; simmer sauce over medium heat until slightly thickened, scraping up any browned bits, about 2 minutes. Stir in chopped chives and tarragon. Season with salt and pepper.

Return pork to skillet. Cook over medium heat just until rewarmed, stirring frequently, about 1 minute. Transfer to platter, sprinkle with parsley, and serve.
