1. Preheat oven to 300 degrees Fahrenheit (150 degrees Celsius).
2. Season lamb with salt, pepper, garlic, and paprika.
3. Add wine, juice, and stock to the pan. Drizzle silan over the lamb, then turn the lamb over so the meat is submerged in the liquid and the bones are facing up.
4. Cover the pan tightly and bake for three hours. Cool slightly, then remove from bones and shred.
