Back in 2011, this version of steak au poivre made with duck breasts was introduced as part of a New Year’s menu. Fancy enough for a gathering, but relaxed enough that it doesn’t feel like too much, you can make it any time you want something a little more special than your average fare.
Heat 1 tablespoon unsalted butter in a saucepan over medium heat. Add the shallot and the reserved duck tenderloins; let them brown well, stirring occasionally, 5 to 8 minutes. Stir in the tomato paste and a small thyme sprig and let them fry for 1 minute.
03Add the broth and 1/4 cup wine, raise the heat to a brisk simmer and let the liquid reduce to about 1 1/4 cups, about 10 minutes. Strain the sauce and return to the heat. Add the remaining 2 tablespoons red wine and the Cognac or brandy and cook for 1 minute more. Dissolve potato starch in 2 tablespoons cold water, then stir the mixture into the sauce. Whisk in the remaining 1 tablespoon butter. Season to taste with salt. (Sauce may be made in advance and reheated, thinned with a little broth.)
04Remove and discard the garlic and thyme sprigs from the breasts. Heat a large, heavy skillet over medium-high. When the pan is hot, lay in the duck breasts, skin-side down, and let them sizzle. Lower the heat to medium and cook for a total of 7 minutes, checking to make sure the skin isn’t browning too quickly. With tongs, turn the breasts over and let them cook another 3 minutes for rare, 4 to 5 minutes for medium-rare. Transfer to a warm platter and let rest for 10 minutes. Slice crosswise, not too thickly, at a slight angle and serve with the sauce.
