Duck Magret With a Blueberry Port Sauce

The first time I tasted duck magret with a fruit-based sauce, it was a revelation. I was in a small bistro in the French countryside, the air thick with the scent of herbs and roasting meat. The richness of the duck, the crispy skin yielding to tender flesh, paired with the bright, sweet-tart sauce – it was an experience that etched itself into my memory. Years later, I still strive to recreate that perfect balance of flavors in my own kitchen, constantly tweaking and experimenting to capture that magic.

Instructions

1. Marinate the Duck: Place the duck breasts in a container or ziplock bag. Add the bruised garlic clove, thyme leaves, and orange zest. Cover the container or seal the bag, and refrigerate for at least a few hours, or preferably overnight, to allow the flavors to infuse into the duck.

2. Render the Duck Fat: Remove the duck breasts from the refrigerator about 30 minutes before cooking to allow them to come to room temperature. Place the duck breast, skin side down, in a large frying pan over medium-high heat. Cook for 8-10 minutes, rendering the fat and crisping the skin. It’s important to regularly drain the rendered fat from the pan during this process. Be careful as the fat will be very hot. The goal is to achieve a deeply golden and crispy skin without burning it.

3. Oven Finish: Transfer the duck breasts to an oven-proof dish placed on a wire rack. This allows for even cooking and helps maintain the crispiness of the skin. Place the dish in a preheated 180°C (350°F) oven for 20-25 minutes. This will result in a medium-rare to medium level of doneness, leaving the center nicely pink.

4. Crisp the Skin (Optional): For extra crispy skin, you can turn on the oven’s grill function for the last few minutes of cooking. Keep a close eye on the duck to prevent the skin from burning. This step is optional but highly recommended for optimal texture.

5. Prepare the Blueberry Port Sauce: While the duck is in the oven, prepare the sauce. In a small saucepan, combine the port wine, half of the blueberries, and the red currant jelly. Heat over medium-high heat and simmer for 8-10 minutes, or until the sauce has reduced to a thin, syrupy consistency.

6. Thicken and Finish the Sauce: In a small bowl, mix the cornflour with a little water to form a slurry. Add the cornflour mixture to the sauce and whisk to dissolve. This will help thicken the sauce slightly. Stir in the Dijon mustard and whisk until fully incorporated. Remove the sauce from the heat and stir in the remaining blueberries. Set aside until ready to serve.

7. Sauté the Spinach: While the duck rests, prepare the spinach. Heat the olive oil in a large pan over medium heat. Add the finely chopped red onion and crushed garlic clove, and cook until the onion has softened, about 3-5 minutes.

8. Wilt the Spinach: Add the butter to the pan with the onions and garlic. Once melted, add the baby spinach leaves and cook until the spinach has wilted and softened, about 2-3 minutes. Season with salt and pepper to taste.

9. Prepare the Rosti Style Potatoes: While the duck rests, prepare the potatoes. Heat the butter in a pan over medium heat. Add the finely chopped onion and crushed garlic clove, and cook until softened, about 3-5 minutes.

10. Cook the Potatoes: Using an absorbent cloth, squeeze any excess liquid from the grated potatoes. Add the squeezed potatoes to the pan with the onions and garlic. Cook until the potato mixture becomes sticky, about 5-7 minutes. Remove the mixture from the pan.

11. Shape and Crisp (Recommended): For best presentation, use egg rings to shape the potato mixture into individual rosti. Place the rings in the pan and fill them with the potato mixture. Cook until browned and crisp on both sides.

12. Quick Method (Alternative): If you’re short on time, you can skip the egg rings. Simply leave the potato mixture in the pan and stir occasionally, cooking until crisp. This method is quicker but will result in a less uniform and somewhat broken presentation.

13. Rest the Duck: Once the duck breasts are cooked, remove them from the oven and let them rest for at least 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product.

14. Serve: Slice the duck breast thinly on the bias. Pour a little blueberry port sauce onto each plate. Arrange the sliced duck breast on top of the sauce. Serve the spinach and rosti style potatoes on the side.

Expert Tips & Tricks

• Scoring the Duck Skin: Before cooking, score the duck skin in a crosshatch pattern. This helps the fat render more easily and promotes even crisping. Be careful not to cut into the flesh of the duck.
• Don’t Overcrowd the Pan: When rendering the duck fat, ensure the pan isn’t overcrowded. Overcrowding will lower the pan’s temperature, causing the duck to steam instead of sear.
• Resting is Crucial: Don’t skip the resting step! Allowing the duck to rest is essential for achieving maximum tenderness and juiciness.
• Adjust Doneness: Adjust the oven cooking time according to your preference for doneness. A meat thermometer inserted into the thickest part of the breast should read 130-135°F for medium-rare, 140-145°F for medium, and 150-155°F for medium-well.
• Port Wine Reduction: The quality of the port wine will significantly impact the flavor of the sauce. Choose a good quality ruby port for the best results.
• Make-Ahead Spinach: The spinach can be prepared ahead of time and reheated just before serving. Be careful not to overcook the spinach, as it can become mushy.
• Rosti Binders: If your potatoes are not sticking together well, you can add a small amount of flour or an egg to the mixture to help bind it.

Serving & Storage Suggestions

Serve the duck magret immediately after cooking for the best flavor and texture. The blueberry port sauce can be made ahead of time and reheated gently. Leftover duck can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a pan or microwave. The sauce can also be stored separately in the refrigerator for up to 5 days. Reheat gently before serving. The Rosti potatoes are best served immediately and are difficult to re-heat.

FAQs (Frequently Asked Questions)

Q: Can I use frozen blueberries for the sauce?

Q: How can I prevent the duck skin from curling up while cooking?
A: Scoring the duck skin before cooking helps to prevent curling. Also, ensure the pan is hot enough before placing the duck in it.

Q: What temperature should the duck be cooked to for medium-rare?
A: The internal temperature of the duck should be 130-135°F (54-57°C) for medium-rare.

Q: Can I make the blueberry port sauce ahead of time?
A: Yes, the sauce can be made ahead of time and stored in the refrigerator for up to 5 days. Reheat gently before serving.
