Season the pork loin with salt, pepper and paprika powder and sauté in oil. Then deglaze with the cream, a little water and the cognac and add the mustard and peppercorns. Cover and cook for about 15 minutes. Then thicken the sauce a little and season to taste.
French fries, potato wedges, hash browns, etc. go very well with this. Depending on your taste, you can of course leave out the peppercorns and replace the pork loin with beef steaks.
