Knuspriger Schweinebauch mit Riesling-Sauerkraut und Trüffel-Kartoffelgratin

Prepare the Pork Belly: Pat the pork belly dry thoroughly. Score the skin in a crosshatch pattern, being careful not to cut into the meat. In a small bowl, combine sea salt, black pepper, crushed juniper berries, crushed caraway seeds, minced garlic, and thyme leaves. Rub this mixture generously all over the pork belly, ensuring it gets into the scores. Place the pork belly, skin-side up, in a roasting dish. Drizzle with olive oil. Refrigerate uncovered for at least 4 hours, or preferably overnight, to allow the skin to dry out.

Braise the Pork Belly: Preheat oven to 160°C (325°F). Remove the pork belly from the refrigerator and let it come to room temperature for 30 minutes. Add 250 ml of chicken or vegetable stock to the roasting dish, ensuring it doesn't touch the pork skin. Cover the dish tightly with foil. Braise in the preheated oven for 2 hours and 30 minutes, or until the meat is very tender.

Prepare the Riesling-Sauerkraut: While the pork belly braises, heat a large Dutch oven or heavy-bottomed pot over medium heat. Add the diced smoked bacon and cook until crispy. Remove the bacon with a slotted spoon and set aside, leaving the rendered fat in the pot. Add the finely diced onion to the pot and sauté until translucent, about 5-7 minutes. Add the rinsed and squeezed sauerkraut, diced apple, bay leaves, juniper berries, and caraway seeds. Stir well. Pour in the Riesling and stock, bring to a simmer, then reduce heat to low, cover, and let it gently simmer for at least 1 hour, or until tender and flavorful. Season with salt and pepper to taste.

Prepare the Truffled Potato Gratin: Increase oven temperature to 180°C (350°F). Lightly butter a gratin dish (approx. 20x20 cm or similar). In a medium bowl, whisk together heavy cream, whole milk, minced garlic, truffle paste (or oil), nutmeg, salt, and pepper. Arrange a single layer of thinly sliced potatoes in the prepared gratin dish. Pour a thin layer of the cream mixture over the potatoes, then sprinkle with a mix of Gruyère and Parmesan cheese. Repeat layering until all potatoes are used, finishing with a generous layer of cheese.

Bake the Gratin: Cover the gratin dish loosely with foil and bake for 40 minutes. Remove the foil and continue baking for another 20-25 minutes, or until the potatoes are tender when pierced with a knife and the top is golden brown and bubbly.

Crisp the Pork Belly Skin: After the braising time, carefully remove the foil from the pork belly. Increase the oven temperature to 220°C (425°F). Drain off most of the braising liquid from the dish (reserve it for a potential sauce, if desired). Return the pork belly to the oven, uncovered, and roast for 20-30 minutes, or until the skin is puffed up, golden, and incredibly crispy. Watch carefully to prevent burning.

Rest and Serve: Once the pork belly skin is crispy, remove it from the oven and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute.

Assemble: Spoon a generous portion of the Riesling-Sauerkraut onto each plate. Place a thick slice of the crispy pork belly next to it. Serve with a portion of the hot Truffled Potato Gratin. Garnish with chopped fresh parsley and chives, and sprinkle the reserved crispy bacon bits over the sauerkraut.
