How to Make It
Preheat the oven to 300°. Season the pork with 1 1/2 tablespoons of smoked salt. In a medium, enameled cast-iron casserole, heat the canola oil until shimmering. Add the pork and cook over moderately high heat, turning, until browned on all sides, 15 minutes. Transfer the pork to a plate.
Add the apple, onion, carrot, celery, garlic and thyme to the casserole and cook over moderate heat until beginning to brown, about 6 minutes. Add the tomato paste and cook, stirring, until it deepens in color, about 2 minutes. Add the wine and bring to a boil. Add the chicken stock, vinegar and honey and bring to a simmer. Add the pork, cover and transfer the casserole to the oven. Braise the pork for about 3 hours, turning once halfway through, until very tender.
Transfer the pork to a plate. Strain the sauce into a large bowl, gently pressing on the solids. Pour the sauce back into the pot. Using 2 forks, shred the pork; discard any large pieces of fat. Transfer the shredded pork to the sauce and stir in the mascarpone. Season the sauce with smoked salt and pepper. Cover and keep warm.
Meanwhile, in a large pot of boiling salted water, cook the pappardelle until al dente. Drain the pasta and transfer to the casserole with the sauce. Toss the pasta with the sauce and the parsley over moderate heat until well coated, about 1 minute. Transfer the pasta to warm bowls. Drizzle with olive oil, sprinkle with smoked salt and serve.
