DUCK SHEET CAKE RECIPES

Steps:

• Use a sharp knife to score the skin side of the duck breasts in 2 directions, about 20 slashes per direction. Season the breasts on both sides with salt and pepper. Reserve in the refrigerator.
• Cut off 1 end so the orange can stand on the cutting board, and slice off 2 (2-inch) strips of zest. Cut the zest into fine julienne, then blanch the zest for 1 minute in the cup of boiling water. Juice the orange, strain the juice into a saucepan, and boil it until it's reduced to about 1 tablespoon.
• If you're using the kumquats instead, cut the round ends off the kumquats and eat or discard them. Set the kumquats on 1 end and use a sharp paring knife to trim the zest off three of them. Cut all the kumquats in half lengthwise, and working over a strainer set in a non-reactive bowl, remove the pulp with a small spoon. Push the pulp against the strainer to extract the juice. (Don't worry if you end up with only a tablespoon or 2.) Place the kumquat zests on a cutting board and slice them into fine julienne. Bring the 1/2 cup water to a boil over high heat, blanch the zests for 1 minute, then drain them in a strainer.
• If you're using concentrated duck broth, reduce it in a small saucepan to about 2 tablespoons until it's lightly syrupy.
• Heat a saute pan over medium to high heat and saute the duck breasts, skin side down, 8 to 10 minutes for the Pekin duck breasts and 12 to 18 minutes for the mallard. Turn the breasts over, adjust the heat to high, and cook for 1 minute for the Pekin duck and 2 minutes for the mallard.
• Pour the fat out of the pan ¿ if it hasn't burned, save it for omelets ¿ and deglaze the pan with the reduced kumquats or orange juice. Use a whisk to add the glaze. Add the sugar, Grand Marnier, kumquat or orange zest, and vinegar, and simmer the sauce for about 30 seconds to cook off the alcohol. At this point, adjust the thickness of the sauce ¿ its consistency is up to you, but many cooks make their sauces too thick; add 1 or 2 teaspoons water to thin it or simmer the sauce for a moment to reduce and thicken it. Whisk in the cold butter, keeping the pan and whisk moving until all the butter melts. (Don't let it sit without whisking or the butter will separate.) Season, to taste, with the pepper, and if necessary, a few more drops of vinegar.
• Slice the breasts crosswise, arrange the slices on individual heated plates, and spoon the sauce over the breasts. Serve hot, with orange wedges if desired.

Steps:

• Preheat the oven to 400 degrees F.
• With a sharp knife score the fat of the duck breasts in a criss-cross pattern. Season the duck with salt and pepper. Warm a heavy bottomed ovenproof skillet over medium heat.
• Place the duck breasts, fat side down, in the skillet to render off the fat, about 6 minutes. Reserve rendered duck fat. Turn the duck breasts over and sear for 1 minute. Turn the fat side down again and place the skillet into the oven to roast for 7 to 9 minutes, until breasts are medium rare. Let the duck breasts rest for 5 minutes then thinly slice.
• Grate the potatoes and squeeze out excess liquid using your hands. Toss the potatoes with the melted butter, rosemary, salt, and pepper. Heat 1 tablespoon of duck fat in a 6-inch cast iron pan over medium-high heat. Press some of the potato mixture into the hot pan to make a 1/4-inch thick cake. Reduce the heat to medium and cook until the rosti is golden brown, about 5 minutes. Flip the rosti in the pan and add more duck fat. Continue cooking until golden and crisp. Place the finished rosti onto an unlined baking sheet and continue cooking the rest of the potato mixture. Reheat rosti in a 400 degree F oven for 10 minutes.
• Combine the brown sugar, raspberry vinegar, red wine vinegar, and white wine vinegar in a medium pot. Place over medium-low heat and stir to dissolve the brown sugar. Simmer for 5 minutes.
• Add the blueberries, onion, green peppercorns, lemon juice, and ginger. Reduce the heat to low and simmer for 45 minutes or until thickened, stirring occasionally to prevent scorching.
• The chutney will keep for several weeks stored in the refrigerator in an airtight container.
