1. To prepare the brine, place 2 springs of each; bay leaves, thyme, rosemary and sage, in a heatproof container. Pour a gallon of hot water over the herbs. Stir in peppercorns, sugar and kosher salt. Allow brine to cool to room temperature. For faster cooling add a scoop of ice to the brining solution
2. Submerge pork in the brine. Cover and chill for up to 12 hours
3. Remove pork from brine. Rinse under cold water and pat dry
4. Preheat oven to 350º
5. In a large ovenproof skillet, heat the vegetable oil over medium-high heat.  Season the pork loin all over generously with salt and pepper. Lay the loin, fat side down in the skillet and cook until golden brown, about 2 minutes
6. Use tongs to turn the meat, and continue to brown it on all sides, about 5-10 minutes per side
7. Transfer the meat to a plate
8. Combine spices for the rub in a coffee grinder or spice grinder and grind until fine and combined. Rub meat generously with spice blend
9. Add the onion, carrot, celery, garlic and herb sprigs to the skillet.  Cook, stirring frequently until the vegetables are softened, about 5 minutes
10. Add the wine to deglaze the pan, scraping the bottom with a wooden spoon to loosen up any browned bits. Add the broth and simmer until the liquid is reduced by about half
11. Return the loin and any collected juices to the skillet.  Add herb sprigs to the liquid and transfer the skillet to the oven. Roast the loin until an instant-read thermometer inserted into the center of the meat registers 145-150º, between 45-60 minutes. Baste the meat with the pan juices every 15 minutes
12. Remove the loin from the oven and allow to rest for 10 minutes
13. Slice and plate atop a mound of the apple garnish. Spoon pan juices over the loin and top with apple sauce to serve
