Season both sides of the pork chops generously with salt. Coarsely crush the peppercorns using a mortar and pestle or the back of a heavy pan, then spread them on a plate. Press each chop firmly into the crushed peppercorns to create an even crust on one side, then flip and repeat on the other side. Cover the chops and let them rest for about 30 minutes at room temperature if time allows, which helps the pepper adhere better and the meat come to an even temperature.
Melt the butter in a large frying pan over medium heat. Add the pepper-crusted pork chops and cook for 5 minutes on each side, or until the meat is just cooked through but still retains its juiciness. Remove the chops from the pan and transfer to a warm plate, covering loosely to keep them hot.
Pour the wine into the same pan and increase the heat to high. Let it boil vigorously until the liquid reduces by half, stirring and scraping up all the flavorful peppercorns and browned bits stuck to the bottom of the pan.
Add the stock to the reduced wine and continue cooking for 5 minutes. Strain the sauce through a fine sieve to remove the peppercorns and any other solids, then return the strained liquid to the pan. Boil for 3 minutes or until the sauce has reduced to a concentrated consistency but isn’t overly thick.
Stir in the cream and cook over high heat, stirring constantly, until the sauce reduces further and thickens to a silky, coating consistency. Return the pork chops to the pan along with any accumulated juices, turning them in the sauce to heat through completely.
Serve the pork chops immediately with a generous drizzle of the peppercorn cream sauce spooned over the top. Accompany with crispy potato wedges and grilled mushrooms for a complete and satisfying meal.
