Instructions
- Prepare the Pork Loin: In a small bowl, whisk together the ground ginger, sugar, star anise, red pepper flakes, soy sauce, rice vinegar, persimmon puree, and sesame oil. Rub the mixture all over the pork loin. Marinate in the refrigerator for at least 2 hours, or preferably overnight.
- Prepare the Rye Berries: Rinse the rye berries and add them to a medium saucepan. Cover with the vegetable broth and bring to a boil. Reduce heat, cover, and simmer for 45-50 minutes, or until the rye berries are tender but still slightly chewy. Drain any excess liquid.
- Preheat oven to 375F (190C).
- Prepare the Sauerkraut: Heat the grapeseed oil in a large skillet over medium heat. Add the onion and cook until softened, about 5 minutes. Add the sauerkraut, juniper berries, and bay leaf. Cook for 5 minutes, stirring occasionally. Add the white wine and chicken broth. Bring to a simmer, then reduce heat and cook for 20 minutes, or until the sauerkraut is tender and the liquid has reduced.
- Prepare the Bchamel Sauce for the Gratin: In a medium saucepan, melt duck fat over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly. Gradually whisk in the milk until smooth. Bring to a simmer, stirring constantly, and cook for 5-7 minutes, or until the sauce has thickened. Stir in the mace. Remove from heat and stir in 3/4 cup of the Gruyere cheese.
- Assemble and Bake the Gratin: Combine the cooked rye berries and the cheese sauce. Pour into a lightly greased 8x8 inch baking dish. Top with the remaining Gruyere cheese and the panko breadcrumbs.
- Bake the Gratin for 20-25 minutes, or until golden brown and bubbly.
- Roast the Pork Loin: Remove the pork loin from the refrigerator 30 minutes before cooking. Place the pork loin on a roasting rack in a baking pan.
- Roast the pork loin for 20-25 minutes per pound, or until a meat thermometer inserted into the thickest part registers 145F (63C).
- Let the pork loin rest for 10 minutes before slicing.
- To Serve: Slice the pork loin and serve over the juniper-spiced sauerkraut. Serve the rye berry gratin on the side. Garnish with sliced scallions.
