Slow-Cooked Duck Breast with Sweet Potato, Exotic Mushrooms and Cocoa Jus
Duck is something that you rarely cook at home, which makes it an excellent choice for special occasions. And this recipe, with its aromatic spices, exotic mushrooms and chocolate, is particularly good for Valentine's Day. The preparation is very simple, but requires a bit of advance planning, as the breast must be lightly cured overnight. This step is important, since it tenderizes the meat and allows the sensuous spices to permeate it. The aromas released during cooking are irresistible!
Serves two
Ingredients:
1 duck magret (fatty breast with skin, from Moulard or other type of duck)
1 medium-sized sweet potato
2 cups mixed mushrooms, e.g., black trumpet, hedgehog, shiitake, oyster, king oyster, cauliflower, porcini
1 oz semi-sweet chocolate
1 cup red wine
1 cup chicken or veal stock
1 tsp cocoa nibs (optional, but they provide an exotic crunch to the mushrooms, not to mention an energy boost!)
1 cup baby spinach
1 tsp fresh-minced ginger
1 tsp minced garlic
1 finely chopped shallot
2 tbsp kosher salt
1 tsp Chinese five-spice powder
Method:
- One day before you plan to cook the meal, clean the breast by trimming any excess fat (there should be ¼ inches left on top) and scoring the fatty side with hatch marks. Liberally sprinkle the flesh side with the five-spice powder and salt, cover with plastic wrap and leave in the refrigerator overnight.
- The following day, rinse the excess salt off under cool water and pat dry with a clean towel.
- Place the sweet potato in an oven heated to 375°F and bake until tender when pierced by a fork (about 45-60 minutes). Remove from the oven, allow to cool slightly, then peel.
- If using dried mushrooms, soak in hot water for 20 minutes to rehydrate. Remove from liquid and pat dry.
- Place the duck breast skin down in a heavy-bottomed saucepan (preferably cast-iron) on medium heat and cook slowly until amber brown and most of the fat has rendered off. Regularly strain the fat to keep the breast from "deep frying." Turn the breast onto the flesh side for a moment to sear in the juice, then turn off the heat and leave the breast skin down in the still-warm pan.
- As the breast is cooking, add 1 tbsp of vegetable oil or some of the rendered duck fat to a large saucepan on high heat and sauté the mushrooms. While they're cooking, add the garlic, ginger and shallot. Season with salt and deglaze with red wine, reduce until almost dry, then add the stock and reduce by half. At this point, check the seasoning and set aside until ready to serve.
- Cut the sweet potato into two medallions and warm in the oven. Reheat the mushrooms, add the spinach and cocoa nibs and melt the chocolate into the mixture. The chocolate will thicken the sauce.
- Slice the duck breast into ½ -inch pieces and arrange on two plates. Add the sweet potato, then spoon the mushroom sauce over the duck and sweet potato.
