Peppered Duck Breast With Red Wine Sauce

Preparation

1. Step 1

   Remove the tenderloins (the thin strips of meat on undersides of the duck breast) and reserve for the sauce. With a sharp knife, trim away any gristle from the undersides of the breasts and trim any excess fat. Score the skin in a diamond pattern, cutting through the fat but not quite reaching the meat. Lightly sprinkle salt on both sides, then rub 1 teaspoon crushed black peppercorns all over. Sprinkle with the garlic and a few thyme sprigs, cover, and leave at room temperature for 1 hour. (For deeper flavor, refrigerate the breasts for several hours or overnight, then return to room temperature before cooking.)

2. Step 2

   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.

3. Step 3

   Add the broth and ¼ cup wine, raise the heat to a brisk simmer and let the liquid reduce to about 1¼ 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.)

4. Step 4

   Remove 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.
